+This document describes system properties that are used for internal
+debugging and instrumentation purposes, along with the system loggers,
+which are used for the same thing.
+
+This document is intended as a developer resource, and it is not
+needed as Nashorn documentation for normal usage. Flags and system
+properties described herein are subject to change without notice.
+
+=====================================
+1. System properties used internally
+=====================================
+
+This documentation of the system property flags assume that the
+default value of the flag is false, unless otherwise specified.
+
+SYSTEM PROPERTY: -Dnashorn.args=<string>
+
+This property takes as its value a space separated list of Nashorn
+command line options that should be passed to Nashorn. This might be
+useful in environments where it is hard to tell how a nashorn.jar is
+launched.
+
+Example:
+
+> java -Dnashorn.args="--lazy-complation --log=compiler" large-java-app-with-nashorn.jar 
+> ant -Dnashorn.args="--log=codegen" antjob
+
+SYSTEM PROPERTY: -Dnashorn.args.prepend=<string>
+
+This property behaves like nashorn.args, but adds the given arguments
+before the existing ones instead of after them. Later arguments will
+overwrite earlier ones, so this is useful for setting default arguments
+that can be overwritten.
+
+
+SYSTEM PROPERTY: -Dnashorn.unstable.relink.threshold=x
+
+NOTE: This property is deprecated in favor of the 
+"--unstable-relink-threshold" command line option. It controls how many
+call site misses are allowed before a callsite is relinked with "apply"
+semantics to never change again. In the case of megamorphic callsites, 
+this is necessary, or the program would spend all its time swapping out 
+callsite targets. When neither the system property nor the command line
+option are specified, defaults to 8, or 16 with optimistic types turned
+on.
+
+
+SYSTEM PROPERTY: -Dnashorn.compiler.splitter.threshold=x
+
+This will change the node weight that requires a subgraph of the IR to
+be split into several classes in order not to run out of bytecode space.
+The default value is 0x8000 (32768).
+
+
+SYSTEM PROPERTY: -Dnashorn.serialize.compression=<x>
+
+This property sets the compression level used when deflating serialized
+AST structures of anonymous split functions. Valid values range from 0 to 9,
+the default value is 4. Higher values will reduce memory size of serialized
+AST but increase CPU usage required for compression.
+
+
+SYSTEM PROPERTY: -Dnashorn.codegen.debug.trace=<x>
+
+See the description of the codegen logger below.
+
+
+SYSTEM PROPERTY: -Dnashorn.fields.objects, -Dnashorn.fields.dual
+
+When the nashorn.fields.objects property is true, Nashorn will always
+use object fields for AccessorProperties, requiring boxing for all
+primitive property values. When nashorn.fields.dual is set, Nashorn
+will always use dual long/object fields, which allows primitives to be
+stored without boxing. When neither system property is set, Nashorn
+chooses a setting depending on the optimistic types setting (dual
+fields when optimistic types are enabled, object-only fields otherwise).
+
+With dual fields, Nashorn uses long fields to store primitive values.
+Ints are represented as the 32 low bits of the long fields. Doubles
+are represented as the doubleToLongBits of their value. This way a
+single field can be used for all primitive types. Packing and
+unpacking doubles to their bit representation is intrinsified by
+the JVM and extremely fast.
+
+In the future, this might complement or be replaced by experimental
+feature sun.misc.TaggedArray, which has been discussed on the mlvm
+mailing list. TaggedArrays are basically a way to share data space
+between primitives and references, and have the GC understand this.
+
+
+SYSTEM PROPERTY: -Dnashorn.compiler.symbol.trace=[<x>[,*]], 
+  -Dnashorn.compiler.symbol.stacktrace=[<x>[,*]]
+
+When this property is set, creation and manipulation of any symbol
+named "x" will show information about when the compiler changes its
+type assumption, bytecode local variable slot assignment and other
+data. This is useful if, for example, a symbol shows up as an Object,
+when you believe it should be a primitive. Usually there is an
+explanation for this, for example that it exists in the global scope
+and type analysis has to be more conservative. 
+
+Several symbols names to watch can be specified by comma separation.
+
+If no variable name is specified (and no equals sign), all symbols
+will be watched
+
+By using "stacktrace" instead of or together with "trace", stack
+traces will be displayed upon symbol changes according to the same
+semantics.
+
+
+SYSTEM PROPERTY: -Dnashorn.lexer.xmlliterals
+
+If this property it set, it means that the Lexer should attempt to
+parse XML literals, which would otherwise generate syntax
+errors. Warning: there are currently no unit tests for this
+functionality.
+
+XML literals, when this is enabled, end up as standard LiteralNodes in
+the IR.
+
+
+SYSTEM_PROPERTY: -Dnashorn.debug
+
+If this property is set to true, Nashorn runs in Debug mode. Debug
+mode is slightly slower, as for example statistics counters are enabled
+during the run. Debug mode makes available a NativeDebug instance
+called "Debug" in the global space that can be used to print property
+maps and layout for script objects, as well as a "dumpCounters" method
+that will print the current values of the previously mentioned stats
+counters.
+
+These functions currently exists for Debug:
+
+"map" - print(Debug.map(x)) will dump the PropertyMap for object x to
+stdout (currently there also exist functions called "embedX", where X
+is a value from 0 to 3, that will dump the contents of the embed pool
+for the first spill properties in any script object and "spill", that
+will dump the contents of the growing spill pool of spill properties
+in any script object. This is of course subject to change without
+notice, should we change the script object layout.
+
+"methodHandle" - this method returns the method handle that is used
+for invoking a particular script function.
+
+"identical" - this method compares two script objects for reference
+equality. It is a == Java comparison
+
+"equals" - Returns true if two objects are either referentially
+identical or equal as defined by java.lang.Object.equals.
+
+"dumpCounters" - will dump the debug counters' current values to
+stdout.
+
+Currently we count number of ScriptObjects in the system, number of
+Scope objects in the system, number of ScriptObject listeners added,
+removed and dead (without references).
+
+We also count number of ScriptFunctions, ScriptFunction invocations
+and ScriptFunction allocations.
+
+Furthermore we count PropertyMap statistics: how many property maps
+exist, how many times were property maps cloned, how many times did
+the property map history cache hit, prevent new allocations, how many
+prototype invalidations were done, how many time the property map
+proto cache hit.
+
+Finally we count callsite misses on a per callsite bases, which occur
+when a callsite has to be relinked, due to a previous assumption of
+object layout being invalidated.
+
+"getContext" - return the current Nashorn context.
+
+"equalWithoutType" - Returns true if if the two objects are both
+property maps, and they have identical properties in the same order,
+but allows the properties to differ in their types.
+
+"diffPropertyMaps" Returns a diagnostic string representing the difference
+of two property maps.
+
+"getClass" - Returns the Java class of an object, or undefined if null.
+
+"toJavaString" - Returns the Java toString representation of an object.
+
+"toIdentString" - Returns a string representation of an object consisting
+of its java class name and hash code.
+
+"getListenerCount" - Return the number of property listeners for a
+script object.
+
+"getEventQueueCapacity" - Get the capacity of the event queue.
+
+"setEventQueueCapacity" - Set the event queue capacity.
+
+"addRuntimeEvent" - Add a runtime event to the runtime event queue.
+The queue has a fixed size (see -Dnashorn.runtime.event.queue.size)
+and the oldest entry will be thrown out of the queue is about to overflow.
+
+"expandEventQueueCapacity" - Expands the event queue capacity,
+or truncates if capacity is lower than current capacity. Then only
+the newest entries are kept.
+
+"clearRuntimeEvents" - Clear the runtime event queue.
+
+"removeRuntimeEvent" - Remove a specific runtime event from the event queue.
+
+"getRuntimeEvents" - Return all runtime events in the queue as an array.
+
+"getLastRuntimeEvent" - Return the last runtime event in the queue.
+
+
+SYSTEM PROPERTY: -Dnashorn.methodhandles.debug.stacktrace
+
+This enhances methodhandles logging (see below) to also dump the
+stack trace for every instrumented method handle operation.
+Warning: This is enormously verbose, but provides a pretty
+decent "grep:able" picture of where the calls are coming from.
+
+
+SYSTEM PROPERTY: -Dnashorn.cce
+
+Setting this system property causes the Nashorn linker to rely on
+ClassCastExceptions for triggering a callsite relink. If not set, the linker
+will add an explicit instanceof guard.
+
+
+SYSTEM PROPERTY: -Dnashorn.spill.threshold=<x>
+
+This property sets the number of fields in an object from which to use
+generic array based spill storage instead of Java fields. The default value
+is 256.
+
+
+SYSTEM PROPERTY: -Dnashorn.tcs.miss.samplePercent=<x>
+
+When running with the trace callsite option (-tcs), Nashorn will count
+and instrument any callsite misses that require relinking. As the
+number of relinks is large and usually produces a lot of output, this
+system property can be used to constrain the percentage of misses that
+should be logged. Typically this is set to 1 or 5 (percent). 1% is the
+default value.
+
+SYSTEM PROPERTY: -Dnashorn.persistent.code.cache
+
+This property can be used to set the directory where Nashorn stores
+serialized script classes generated with the -pcc/--persistent-code-cache
+option. The default directory name is "nashorn_code_cache".
+
+
+SYSTEM PROPERTY: -Dnashorn.typeInfo.maxFiles
+
+Maximum number of files to store in the type info cache. The type info cache
+is used to cache type data of JavaScript functions when running with
+optimistic types (-ot/--optimistic-types). There is one file per JavaScript
+function in the cache.
+
+The default value is 0 which means the feature is disabled. Setting this
+to something like 20000 is probably good enough for most applications and
+will usually cap the cache directory to about 80MB presuming a 4kB
+filesystem allocation unit. Set this to "unlimited" to run without limit.
+
+If the value is not 0 or "unlimited", Nashorn will spawn a cleanup thread
+that makes sure the number of files in the cache does not exceed the given
+value by deleting the least recently modified files.
+
+
+SYSTEM PROPERTY: -Dnashorn.typeInfo.cacheDir
+
+This property can be used to set the directory where Nashorn stores the
+type info cache when -Dnashorn.typeInfo.maxFiles is set to a nonzero
+value. The default location is platform specific. On Windows, it is
+"${java.io.tmpdir}\com.oracle.java.NashornTypeInfo". On Linux and
+Solaris it is "~/.cache/com.oracle.java.NashornTypeInfo". On Mac OS X,
+it is "~/Library/Caches/com.oracle.java.NashornTypeInfo".
+
+
+SYSTEM PROPERTY: -Dnashorn.typeInfo.cleanupDelaySeconds=<value>
+
+This sets the delay between cleanups of the typeInfo cache, in seconds.
+The default delay is 20 seconds.
+
+
+SYSTEM PROPERTY: -Dnashorn.profilefile=<filename>
+
+When running with the profile callsite options (-pcs), Nashorn will
+dump profiling data for all callsites to stderr as a shutdown hook. To
+instead redirect this to a file, specify the path to the file using
+this system property.
+
+
+SYSTEM_PROPERTY: -Dnashorn.regexp.impl=[jdk|joni]
+
+This property defines the regular expression engine to be used by
+Nashorn. Set this flag to "jdk" to get an implementation based on the
+JDK's java.util.regex package. Set this property to "joni" to install
+an implementation based on Joni, the regular expression engine used by
+the JRuby project. The default value for this flag is "joni"
+
+SYSTEM PROPERTY: -Dnashorn.runtime.event.queue.size=<value>
+
+Nashorn provides a fixed sized runtime event queue for debugging purposes.
+See -Dnashorn.debug for methods to access the event queue.
+The default value is 1024.
+
+SYSTEM PROPERTY: -Dnashorn.anonymous.classes.threshold=<value>
+
+Nashorn can use anonymous classes for loading compiled scripts, depending
+on the --anonymous-classes=[auto|true|false] option. Anonymous classes load
+faster, but the loaded classes get less optimization applied to them and
+therefore usually run slower. In the default "auto" setting, scripts are
+loaded as anonymous classes if the script size does not exceed 512 bytes.
+The above system property allows to set this threshold to a user defined
+value.
+
+===============
+2. The loggers.
+===============
+
+It is very simple to create your own logger. Use the DebugLogger class
+and give the subsystem name as a constructor argument.
+
+The Nashorn loggers can be used to print per-module or per-subsystem
+debug information with different levels of verbosity. The loggers for
+a given subsystem are available are enabled by using
+
+--log=<systemname>[:<level>]
+
+on the command line.
+
+Here <systemname> identifies the name of the subsystem to be logged
+and the optional colon and level argument is a standard
+java.util.logging.Level name (severe, warning, info, config, fine,
+finer, finest). If the level is left out for a particular subsystem,
+it defaults to "info". Any log message logged as the level or a level
+that is more important will be output to stderr by the logger.
+
+Several loggers can be enabled by a single command line option, by
+putting a comma after each subsystem/level tuple (or each subsystem if
+level is unspecified). The --log option can also be given multiple
+times on the same command line, with the same effect.
+
+For example: --log=codegen,fields:finest is equivalent to
+--log=codegen:info --log=fields:finest
+
+The following is an incomplete list of subsystems that currently
+support logging. Look for classes implementing
+jdk.nashorn.internal.runtime.logging.Loggable for more loggers.
+
+
+* compiler
+
+The compiler is in charge of turning source code and function nodes
+into byte code, and installs the classes into a class loader
+controlled from the Context. Log messages are, for example, about
+things like new compile units being allocated. The compiler has global
+settings that all the tiers of codegen (e.g. Lower and CodeGenerator)
+use.s
+
+
+* recompile
+
+This logger shows information about recompilation of scripts and
+functions at runtime. Recompilation may happen because a function
+was called with different parameter types, or because an optimistic
+assumption failed while executing a function with -ot/--optimistic-types.
+
+
+* codegen
+
+The code generator is the emitter stage of the code pipeline, and
+turns the lowest tier of a FunctionNode into bytecode. Codegen logging
+shows byte codes as they are being emitted, line number information
+and jumps. It also shows the contents of the bytecode stack prior to
+each instruction being emitted. This is a good debugging aid. For
+example:
+
+[codegen] #41                       line:2 (f)_afc824e 
+[codegen] #42                           load symbol x slot=2 
+[codegen] #43  {1:O}                    load int 0 
+[codegen] #44  {2:I O}                  dynamic_runtime_call GT:ZOI_I args=2 returnType=boolean 
+[codegen] #45                              signature (Ljava/lang/Object;I)Z 
+[codegen] #46  {1:Z}                    ifeq  ternary_false_5402fe28 
+[codegen] #47                           load symbol x slot=2 
+[codegen] #48  {1:O}                    goto ternary_exit_107c1f2f 
+[codegen] #49                       ternary_false_5402fe28 
+[codegen] #50                           load symbol x slot=2 
+[codegen] #51  {1:O}                    convert object -> double 
+[codegen] #52  {1:D}                    neg 
+[codegen] #53  {1:D}                    convert double -> object 
+[codegen] #54  {1:O}                ternary_exit_107c1f2f 
+[codegen] #55  {1:O}                    return object 
+
+shows a ternary node being generated for the sequence "return x > 0 ?
+x : -x"
+
+The first number on the log line is a unique monotonically increasing
+emission id per bytecode. There is no guarantee this is the same id
+between runs.  depending on non deterministic code
+execution/compilation, but for small applications it usually is. If
+the system variable -Dnashorn.codegen.debug.trace=<x> is set, where x
+is a bytecode emission id, a stack trace will be shown as the
+particular bytecode is about to be emitted. This can be a quick way to
+determine where it comes from without attaching the debugger. "Who
+generated that neg?"
+
+The --log=codegen option is equivalent to setting the system variable
+"nashorn.codegen.debug" to true.
+
+* fold
+
+Shows constant folding taking place before lowering
+
+* lower
+
+This is the first lowering pass.
+
+Lower is a code generation pass that turns high level IR nodes into
+lower level one, for example substituting comparisons to RuntimeNodes
+and inlining finally blocks.
+
+Lower is also responsible for determining control flow information
+like end points.
+
+* symbols
+
+The symbols logger tracks the assignment os symbols to identifiers.
+
+* scopedepths
+
+This logs the calculation of scope depths for non-local symbols.
+
+* fields
+
+The --log=fields option (at info level) is equivalent to setting the
+system variable "nashorn.fields.debug" to true. At the info level it
+will only show info about type assumptions that were invalidated. If
+the level is set to finest, it will also trace every AccessorProperty
+getter and setter in the program, show arguments, return values
+etc. It will also show the internal representation of respective field
+(Object in the normal case, unless running with the dual field
+representation)
+
+* time
+
+This enables timers for various phases of script compilation. The timers
+will be dumped when the Nashorn process exits. We see a percentage value
+of how much time was spent not executing bytecode (i.e. compilation and
+internal tasks) at the end of the report. 
+
+A finer level than "info" will show individual compilation timings as they
+happen.
+
+Here is an example:
+
+[time] Accumulated complation phase Timings:
+[time] 
+[time] 'JavaScript Parsing'              1076 ms
+[time] 'Constant Folding'                 159 ms
+[time] 'Control Flow Lowering'            303 ms
+[time] 'Program Point Calculation'        282 ms
+[time] 'Builtin Replacement'               71 ms
+[time] 'Code Splitting'                   670 ms
+[time] 'Symbol Assignment'                474 ms
+[time] 'Scope Depth Computation'          249 ms
+[time] 'Optimistic Type Assignment'       186 ms
+[time] 'Local Variable Type Calculation'  526 ms
+[time] 'Bytecode Generation'             5177 ms
+[time] 'Class Installation'              1854 ms
+[time] 
+[time] Total runtime: 11994 ms (Non-runtime: 11027 ms [91%])
+
+* methodhandles
+
+If this logger is enabled, each MethodHandle related call that uses
+the java.lang.invoke package gets its MethodHandle intercepted and an
+instrumentation printout of arguments and return value appended to
+it. This shows exactly which method handles are executed and from
+where. (Also MethodTypes and SwitchPoints).
+
+* classcache
+
+This logger shows information about reusing code classes using the
+in-memory class cache. Nashorn will try to avoid compilation of
+scripts by using existing classes. This can significantly improve
+performance when repeatedly evaluating the same script.
+
+=======================
+3. Undocumented options
+=======================
+
+Here follows a short description of undocumented options for Nashorn.
+To see a list of all undocumented options, use the (undocumented) flag
+"-xhelp".
+
+i.e. jjs -xhelp or java -jar nashorn.jar -xhelp
+
+Undocumented options are not guaranteed to work, run correctly or be
+bug free. They are experimental and for internal or debugging use.
+They are also subject to change without notice.
+
+In practice, though, all options below not explicitly documented as
+EXPERIMENTAL can be relied upon, for example --dump-on-error is useful
+for any JavaScript/Nashorn developer, but there is no guarantee.

+<h2><span>Who is the Java Scripting API For?</span></h2>
+<span>Some useful characteristics of scripting languages
+are:</span>
+<ul>
+<li><span><b>Convenience</b>: Most scripting languages are
+dynamically typed. You can usually create new variables without
+declaring the variable type, and you can reuse variables to store
+objects of different types. Also, scripting languages tend to
+perform many type conversions automatically, for example,
+converting the number 10 to the text "10" as necessary.</span></li>
+<li><span><b>Developing rapid prototypes</b>: You can avoid the
+edit-compile-run cycle and just use edit-run!</span></li>
+<li><span><b>Application extension/customization</b>: You can
+"externalize" parts of your application - like configuration
+scripts, business logic/rules and math expressions for financial
+applications.</span></li>
+<li><span><b>"Command line" shells for applications</b> -for
+debugging, runtime/deploy time configuration etc. Most applications
+have a web-based GUI configuaration tool these days. But
+sysadmins/deployers frequently prefer command line tools. Instead
+of inventing ad-hoc scripting language for that purpose, a
+"standard" scripting language can be used.</span></li>
+</ul>
+<p><span>The Java<font size="-1"><sup>TM</sup></font> Scripting API
+is a scripting language indepedent framework for using script
+engines from Java code. With the Java Scripting API, it is possible
+to write customizable/extendable applications in the Java language
+and leave the customization scripting language choice to the end
+user. The Java application developer need not choose the extension
+language during development. If you write your application with
+JSR-223 API, then your users can use any JSR-223 compliant
+scripting language.</span></p>
+<hr>
+<span><a name="package" id="package"></a></span>
+<h2><span>Scripting Package</span></h2>
+<p><span>The Java Scripting functionality is in the <code><a href="http://docs.oracle.com/javase/9/docs/api/javax/script/package-summary.html">javax.script</a></code>
+package. This is a relatively small, simple API. The starting point
+of the scripting API is the <code>ScriptEngineManager</code> class.
+A ScriptEngineManager object can discover script engines through
+the jar file service discovery mechanism. It can also instantiate
+ScriptEngine objects that interpret scripts written in a specific
+scripting language. The simplest way to use the scripting API is as
+follows:</span></p>
+<ol>
+<li><span>Create a <code>ScriptEngineManager</code>
+object.</span></li>
+<li><span>Get a <code>ScriptEngine</code> object from the
+manager.</span></li>
+<li><span>Evaluate script using the <code>ScriptEngine</code>'s
+<code>eval</code> methods.</span></li>
+</ol>
+<p><span>Now, it is time to look at some sample code. While it is
+not mandatory, it may be useful to know a bit of JavaScript to read
+these examples.</span></p>
+<hr>
+<span><a name="examples" id="examples"></a></span>
+<h2><span>Examples</span></h2>
+<span><a name="helloworld" id="helloworld"></a></span>
+<h3><span>"Hello, World"</span></h3>
+<p><span>From the <code>ScriptEngineManager</code> instance, we
+request a JavaScript engine instance using
+<code>getEngineByName</code> method. On the script engine, the
+<code>eval</code> method is called to execute a given String as
+JavaScript code! For brevity, in this as well as in subsequent
+examples, we have not shown exception handling. There are checked
+and runtime exceptions thrown from <code>javax.script</code> API.
+Needless to say, you have to handle the exceptions
+appropriately.</span></p>
+<pre>
+<span><code>
+// <a href="source/EvalScript.java">EvalScript.java</a>
+
+import javax.script.*;
+public class EvalScript {

+<h3>Evaluating a Script File</h3>
+<p>In this example, we call the <code>eval</code> method that
+accepts <code>java.io.Reader</code> for the input source. The
+script read by the given reader is executed. This way it is
+possible to execute scripts from files, URLs and resources by
+wrapping the relevant input stream objects as readers.</p>
+<pre>
+<code>
+// <a href="source/EvalFile.java">EvalFile.java</a>

+<h3>Script Variables</h3>
+<p>When you embed script engines and scripts with your Java
+application, you may want to expose your application objects as
+global variables to scripts. This example demonstrates how you can
+expose your application objects as global variables to a script. We
+create a <code>java.io.File</code> in the application and expose
+the same as a global variable with the name "file". The script can
+access the variable - for example, it can call public methods on
+it. Note that the syntax to access Java objects, methods and fields
+is dependent on the scripting language. JavaScript supports the
+most "natural" Java-like syntax.</p>
+<p>
+Nashorn script engine pre-defines two global variables named "context"
+and "engine". The "context" variable is of type javax.script.ScriptContext
+and refers to the current ScriptContext instance passed to script engine's
+eval method. The "engine" variable is of type javax.script.ScriptEngine and
+refers to the current nashorn script engine instance evaluating the script.
+Both of these variables are non-writable, non-enumerable and non-configurable
+- which implies script code can not write overwrite the value, for..loop iteration
+on global object will not iterate these variables and these variables can not be
+deleted by script.
+<pre><code>
+// <a href="source/ScriptVars.java">ScriptVars.java</a>
+
+import javax.script.*;
+import java.io.*;
+
+public class ScriptVars { 
+    public static void main(String[] args) throws Exception {
+        ScriptEngineManager manager = new ScriptEngineManager();
+        ScriptEngine engine = manager.getEngineByName("nashorn");
+
+        File f = new File("test.txt");
+        // expose File object as variable to script
+        engine.<span class="methodref">put</span>("file", f);
+
+        // evaluate a script string. The script accesses "file" 
+        // variable and calls method on it
+        engine.eval("print(file.getAbsolutePath())");
+    }
+}
+
+</code>

+<a name="invoke" id="invoke"></a>
+<h3>Invoking Script Functions and Methods</h3>
+<p>Sometimes you may want to call a specific scripting function
+repeatedly - for example, your application menu functionality might
+be implemented by a script. In your menu's action event handler you
+may want to call a specific script function. The following example
+demonstrates invoking a specific script function from Java
+code.</p>
+<pre><code>
+// <a href="source/InvokeScriptFunction.java">InvokeScriptFunction.java</a>
+
+import javax.script.*;
+
+public class InvokeScriptFunction {
+    public static void main(String[] args) throws Exception {
+        ScriptEngineManager manager = new ScriptEngineManager();
+        ScriptEngine engine = manager.getEngineByName("nashorn");
+
+        // JavaScript code in a String
+        String script = "function hello(name) { print('Hello, ' + name); }";
+        // evaluate script
+        engine.eval(script);
+
+        // <code>javax.script.Invocable</code> is an optional interface.
+        // Check whether your script engine implements it or not!
+        // Note that the JavaScript engine implements Invocable interface.
+        <span class="classref">Invocable</span> inv = (Invocable) engine;
+
+        // invoke the global function named "hello"
+        inv.<span class="methodref">invokeFunction</span>("hello", "Scripting!!" );
+    }
+}
+
+</code>
+</pre>
+<p>If your scripting language is object based (like JavaScript) or
+object-oriented, then you can invoke a script method on a script
+object.</p>
+<pre><code>
+// <a href="source/InvokeScriptMethod.java">InvokeScriptMethod.java</a>
+
+import javax.script.*;
+
+public class InvokeScriptMethod {
+    public static void main(String[] args) throws Exception {
+        ScriptEngineManager manager = new ScriptEngineManager();
+        ScriptEngine engine = manager.getEngineByName("nashorn");
+
+        // JavaScript code in a String. This code defines a script object 'obj'
+        // with one method called 'hello'.        
+        String script = "var obj = new Object(); obj.hello = function(name) { print('Hello, ' + name); }";
+        // evaluate script
+        engine.eval(script);
+
+        // <code>javax.script.Invocable</code> is an optional interface.
+        // Check whether your script engine implements or not!
+        // Note that the JavaScript engine implements Invocable interface.
+        <span class="classref">Invocable</span> inv = (Invocable) engine;
+
+        // get script object on which we want to call the method
+        Object obj = engine.<span class="methodref">get</span>("obj");
+
+        // invoke the method named "hello" on the script object "obj"
+        inv.<span class="methodref">invokeMethod</span>(obj, "hello", "Script Method !!" );
+    }
+}
+
+</code>

+<h3>Implementing Java Interfaces by Scripts</h3>
+<p>Instead of calling specific script functions from Java,
+sometimes it is convenient to implement a Java interface by script
+functions or methods. Also, by using interfaces we can avoid having
+to use the <code>javax.script</code> API in many places. We can get
+an interface implementor object and pass it to various Java APIs.
+The following example demonstrates implementing the
+<code>java.lang.Runnable</code> interface with a script.</p>
+<pre><code>
+// <a href="source/RunnableImpl.java">RunnableImpl.java</a>
+
+import javax.script.*;
+
+public class RunnableImpl {
+    public static void main(String[] args) throws Exception {
+        ScriptEngineManager manager = new ScriptEngineManager();
+        ScriptEngine engine = manager.getEngineByName("nashorn");
+
+        // JavaScript code in a String
+        String script = "function run() { print('run called'); }";
+
+        // evaluate script
+        engine.eval(script);
+
+        <span class="classref">Invocable</span> inv = (Invocable) engine;
+
+        // get Runnable interface object from engine. This interface methods
+        // are implemented by script functions with the matching name.
+        Runnable r = inv.<span class="methodref">getInterface</span>(Runnable.class);
+
+        // start a new thread that runs the script implemented
+        // runnable interface
+        Thread th = new Thread(r);
+        th.start();
+        th.join();
+    }
+}
+</code>
+</pre>
+<p>If your scripting language is object-based or object-oriented,
+it is possible to implement a Java interface by script methods on
+script objects. This avoids having to call script global functions
+for interface methods. The script object can store the "state"
+associated with the interface implementor.</p>
+<pre><code>
+// <a href="source/RunnableImplObject.java">RunnableImplObject.java</a>
+
+import javax.script.*;
+
+public class RunnableImplObject {
+    public static void main(String[] args) throws Exception {
+        ScriptEngineManager manager = new ScriptEngineManager();
+        ScriptEngine engine = manager.getEngineByName("nashorn");
+
+        // JavaScript code in a String
+        String script = "var obj = new Object(); obj.run = function() { print('run method called'); }";
+
+        // evaluate script
+        engine.eval(script);
+
+        // get script object on which we want to implement the interface with
+        Object obj = engine.<span class="methodref">get</span>("obj");
+
+        <span class="classref">Invocable</span> inv = (Invocable) engine;
+
+        // get Runnable interface object from engine. This interface methods
+        // are implemented by script methods of object 'obj'
+        Runnable r = inv.<span class="methodref">getInterface</span>(obj, Runnable.class);
+
+        // start a new thread that runs the script implemented
+        // runnable interface
+        Thread th = new Thread(r);
+        th.start();
+        th.join();
+    }
+}

+<h3>Multiple Scopes for Scripts</h3>
+<p>In the <a href="#scriptvars">script variables</a> example, we
+saw how to expose application objects as script global variables.
+It is possible to expose multiple global "scopes" for scripts. A
+single scope is an instance of <code>javax.script.Bindings</code>.
+This interface is derived from <code>java.util.Map&lt;String,
+Object&gt;</code>. A scope a set of name-value pairs where name is
+any non-empty, non-null String.
+<code>javax.script.ScriptContext</code> interface supports multiple
+scopes with associated Bindings for each
+scope. By default, every script engine has a default script
+context. The default script context has atleast one scope called
+"ENGINE_SCOPE". Various scopes supported by a script context are
+available through <code>getScopes</code> method.</p>
+<pre><code>
+// <a href="source/MultiScopes.java">MultiScopes.java</a>
+
+import javax.script.*;
+
+public class MultiScopes {
+    public static void main(String[] args) throws Exception {
+        ScriptEngineManager manager = new ScriptEngineManager();
+        ScriptEngine engine = manager.getEngineByName("nashorn");
+
+        engine.put("x", "hello");
+        // print global variable "x"
+        engine.eval("print(x);");
+        // the above line prints "hello"
+
+        // Now, pass a different script context
+        <span class="classref">ScriptContext</span> newContext = new <span class="classref">SimpleScriptContext</span>();
+        newContext.setBindings(engine.createBindings(), ScriptContext.ENGINE_SCOPE);
+        <span class="classref">Bindings</span> engineScope = newContext.<span class="methodref">getBindings</span>(ScriptContext.ENGINE_SCOPE);
+
+        // add new variable "x" to the new engineScope        
+        engineScope.<span class="methodref">put</span>("x", "world");
+
+        // execute the same script - but this time pass a different script context
+        engine.eval("print(x);", newContext);
+        // the above line prints "world"
+    }

+<p>Oracle's implementation of JDK 8 is co-bundled with the Nashorn ECMAScript
+script engine.
+<hr>
+<a name="jstojava" id="jstojava"></a>
+<h2>JavaScript to Java Communication</h2>
+<p>For the most part, accessing Java classes, objects and methods
+is straightforward. In particular field and method access from
+JavaScript is the same as it is from Java. We highlight important
+aspects of JavaScript Java access here. 
+The following examples are JavaScript snippets accessing Java. This
+section requires knowledge of JavaScript. This section can be
+skipped if you are planning to use some other JSR-223 scripting
+language rather than JavaScript.</p>
+<hr>
+<a name="jsjavaclass" id=jsjavalass"></a>
+<h3>Accessing Java Classes</h3>
+<pre>
+<code>
+// <a href="source/javatypes.js">javatypes.js</a>
+
+ var arrayListType = Java.type("java.util.ArrayList")
+ var intType = Java.type("int")
+ var stringArrayType = Java.type("java.lang.String[]")
+ var int2DArrayType = Java.type("int[][]")
+</code>
+</pre> 
+
+Note that the name of the type is always a string for a fully qualified name. You can use any of these expressions to create new instances, e.g.:
+
+<pre><code>
+ var anArrayList = new (Java.type("java.util.ArrayList"))
+</code></pre> 
+
+or
+
+<pre><code>
+ var ArrayList = Java.type("java.util.ArrayList")
+ var anArrayList = new ArrayList
+ var anArrayListWithSize = new ArrayList(16)
+</code></pre> 
+
+In the special case of inner classes, you can either use the JVM fully qualified name, meaning using the dollar sign in the class name, or you can use the dot:
+
+<pre><code>
+ var ftype = Java.type("java.awt.geom.Arc2D$Float")
+</code></pre> 
+ 
+and
+ 
+<pre><code>
+ var ftype = Java.type("java.awt.geom.Arc2D.Float")
+</code></pre> 
+
+both work. Note however that using the dollar sign is faster, as Java.type first tries to resolve the class name as it is originally specified, and the internal JVM names for inner classes use the dollar sign. If you use the dot, Java.type will internally get a ClassNotFoundException and subsequently retry by changing the last dot to dollar sign. As a matter of fact, it'll keep replacing dots with dollar signs until it either successfully loads the class or runs out of all dots in the name. This way it can correctly resolve and load even multiply nested inner classes with the dot notation. Again, this will be slower than using the dollar signs in the name. An alternative way to access the inner class is as a property of the outer class:
+
+<pre><code>
+ var arctype = Java.type("java.awt.geom.Arc2D")
+ var ftype = arctype.Float
+</code></pre> 
+<p>
+You can access both static and non-static inner classes. If you want to create an instance of a non-static inner class, remember to pass an instance of its outer class as the first argument to the constructor.
+</p>
+<p>
+In addition to creating new instances, the type objects returned from <code>Java.type</code> calls can also be used to access the
+static fields and methods of the classes:
+<pre><code>
+ var File = Java.type("java.io.File")
+ File.createTempFile("nashorn", ".tmp")
+</code></pre> 
+<p>
+Methods with names of the form <code>isXxx()</code>, <code>getXxx()</code>, and <code>setXxx()</code> can also be used as properties, for both instances and statics.
+</p>
+<p>
+A type object returned from <code>Java.type</code> is distinct from a <code>java.lang.Class</code> object. You can obtain one from the other using properties <code>class</code> and <code>static</code> on them.
+<pre><code>
+ var ArrayList = Java.type("java.util.ArrayList")
+ var a = new ArrayList
+
+ // All of the following print true:
+ print("Type acts as target of instanceof: " + (a instanceof ArrayList))
+ print("Class doesn't act as target of instanceof: " + !(a instanceof a.getClass()))
+ print("Type is not same as instance's getClass(): " + (a.getClass() !== ArrayList))
+ print("Type's `class` property is same as instance getClass(): " + (a.getClass() === ArrayList.class))
+ print("Type is same as instance getClass()'s `static` property: " + (a.getClass().static === ArrayList))
+</code></pre> 
+<p>
+You can think of the type object as similar to the class names as used in Java source code: you use them as the
+arguments to the <code>new</code> and <code>instanceof</code> operators and as the namespace for the static fields
+and methods, but they are different than the runtime <code>Class</code> objects returned by <code>getClass()</code> calls.
+Syntactically and semantically, this separation produces code that is most similar to Java code, where a distinction
+between compile-time class expressions and runtime class objects also exists. (Also, Java can't have the equivalent of <code>static</code>
+property on a <code>Class</code> object since compile-time class expressions are never reified as objects).

+<h3>Importing Java Packages, Classes</h3>
+<p>The built-in functions <code>importPackage</code> (in compatibility script) and
+<code>importClass</code> can be used to import Java packages and
+classes.</p>
+<pre><code>
+
+// <a href="source/importpackageclass.js">importpackageclass.js</a>
+
+// load compatibility script
+load("nashorn:mozilla_compat.js");
+// Import Java packages and classes 
+// like import package.*; in Java
+<span class="functionref">importPackage</span>(java.awt);
+// like import java.awt.Frame in Java
+<span class="functionref">importClass</span>(java.awt.Frame);
+// Create Java Objects by "new ClassName"
+var frame = new java.awt.Frame("hello");
+// Call Java public methods from script
+frame.setVisible(true);
+// Access "JavaBean" properties like "fields"
+print(frame.title);
+</code>
+</pre>
+<p>The <span class="objectref">Packages</span> global variable can
+be used to access Java packages. Examples:
+<code>Packages.java.util.Vector</code>,
+<code>Packages.javax.swing.JFrame</code>. Please note that "java"
+is a shortcut for "Packages.java". There are equivalent shortcuts
+for javax, org, edu, com, net prefixes, so pratically all JDK
+platform classes can be accessed without the "Packages" prefix.</p>
+<p>Note that java.lang is not imported by default (unlike Java)
+because that would result in conflicts with JavaScript's built-in
+Object, Boolean, Math and so on.</p>
+<p><code>importPackage</code> and <code>importClass</code>
+functions "pollute" the global variable scope of JavaScript. To
+avoid that, you may use <span class="functionref">JavaImporter</span>.</p>
+<pre><code>
+
+// <a href="source/javaimporter.js">javaimporter.js</a>
+
+// create JavaImporter with specific packages and classes to import
+
+var SwingGui = new <span class="functionref">JavaImporter</span>(javax.swing,
+                            javax.swing.event,
+                            javax.swing.border,
+                            java.awt.event);
+with (SwingGui) {
+    // within this 'with' statement, we can access Swing and AWT
+    // classes by unqualified (simple) names.
+
+    var mybutton = new JButton("test");
+    var myframe = new JFrame("test");
+}
+
+</code>
+</pre>
+<hr>
+<a name="jsarrays" id="jsarrays"></a>
+<h3>Creating, Converting and Using Java Arrays</h3>
+<p>
+Array element access or length access is the same as in Java.</p>
+<pre><code>
+// <a href="source/javaarray.js">javaarray.js</a>
+
+// create Java String array of 5 elements
+var StringArray = Java.type("java.lang.String[]");
+var a = new StringArray(5);
+
+// Accessing elements and length access is by usual Java syntax
+a[0] = "scripting is great!";
+print(a.length);
+print(a[0]);
+</code>
+</pre>
+<p>
+It is also possible to convert between JavaScript and Java arrays.
+Given a JavaScript array and a Java type, <code>Java.to</code> returns a Java array with the same initial contents, and with the specified array type. 
+</p>
+<pre><code>
+ var anArray = [1, "13", false]
+ var javaIntArray = Java.to(anArray, "int[]")
+ print(javaIntArray[0]) // prints 1
+ print(javaIntArray[1]) // prints 13, as string "13" was converted to number 13 as per ECMAScript ToNumber conversion
+ print(javaIntArray[2]) // prints 0, as boolean false was converted to number 0 as per ECMAScript ToNumber conversion
+</code></pre>
+<p>
+You can use either a string or a type object returned from <code>Java.type()</code> to specify the type of the array. 
+You can also omit the array type, in which case a <code>Object[]</code> will be created.
+</p>
+<p>
+Given a Java array or Collection, <code>Java.from</code> returns a JavaScript array with a shallow copy of its contents. Note that in most cases, you can use Java arrays and lists natively in Nashorn; in cases where for some reason you need to have an actual JavaScript native array (e.g. to work with the array comprehensions functions), you will want to use this method.
+</p>
+<pre><code>
+var File = Java.type("java.io.File");
+var listCurDir = new File(".").listFiles();
+var jsList = Java.from(listCurDir);
+print(jsList);
+</code></pre>
+<hr>
+<a name="jsimplement" id="jsimplement"></a>
+<h3>Implementing Java interfaces</h3>
+<p>A Java interface can be implemented in JavaScript by using a
+Java anonymous class-like syntax:</p>
+<pre><code>
+// <a href="source/runnable.js">runnable.js</a>
+
+var r  = new java.lang.Runnable() {
+    run: function() {
+        print("running...\n");
+    }
+};
+
+// "r" can be passed to Java methods that expect java.lang.Runnable
+var th = new java.lang.Thread(r);
+th.start();
+th.join();
+</code>
+</pre>
+<p>When an interface with a single method is expected, you can pass
+a script function directly.(auto conversion)</p>
+<pre><code>
+// <a href="source/samfunc.js">samfunc.js</a>
+
+function func() {
+     print("I am func!");
+}
+
+// pass script function for java.lang.Runnable argument
+var th = new java.lang.Thread(func);
+th.start();
+th.join();
+</code>
+</pre>
+<hr>
+<a name="jsextendabstract" id="jsextendabstract"></a>
+<h3>Extending Abstract Java Classes</h3>
+<p>
+If a Java class is abstract, you can instantiate an anonymous subclass of it using an argument list that is applicable to any of its public or protected constructors, but inserting a JavaScript object with functions properties that provide JavaScript implementations of the abstract methods. If method names are overloaded, the JavaScript function will provide implementation for all overloads. E.g.:
+</p>
+
+<pre><code>
+ var TimerTask =  Java.type("java.util.TimerTask")
+ var task = new TimerTask({ run: function() { print("Hello World!") } })
+</code></pre>
+
+Nashorn supports a syntactic extension where a "new" expression followed by an argument is identical to invoking the constructor and passing the argument to it, so you can write the above example also as:
+
+<pre><code>
+ var task = new TimerTask {
+     run: function() {
+       print("Hello World!")
+     }
+ }
+</code></pre>
+
+which is very similar to Java anonymous inner class definition. On the other hand, if the type is an abstract type with a single abstract method (commonly referred to as a "SAM type") or all abstract methods it has share the same overloaded name), then instead of an object, you can just pass a function, so the above example can become even more simplified to:
+
+<pre><code>
+ var task = new TimerTask(function() { print("Hello World!") })
+</code></pre>
+
+<p>
+Note that in every one of these cases if you are trying to instantiate an abstract class that has constructors that take some arguments, you can invoke those simply by specifying the arguments after the initial implementation object or function.
+</p>
+<p>
+The use of functions can be taken even further; if you are invoking a Java method that takes a SAM type, you can just pass in a function object, and Nashorn will know what you meant:
+</p>
+<code><pre>
+ Java.type("java.util.Timer")
+ timer.schedule(function() { print("Hello World!") })
+</code></pre>
+
+Here, <code>Timer.schedule()</code> expects a <code>TimerTask</code> as its argument, so Nashorn creates an instance of a TimerTask subclass and uses the passed function to implement its only abstract method, run(). In this usage though, you can't use non-default constructors; the type must be either an interface, or must have a protected or public no-arg constructor.

+<a name="jsextendconcrete" id="jsextendconcrete"></a>
+<h3>Extending Concrete Java Classes</h3>
+<p>
+To extend a concrete Java class, you have to use <code>Java.extend</code> function.
+<code>Java.extend</code> returns a type object for a subclass of the specified Java class (or implementation of the specified interface) that acts as a script-to-Java adapter for it.  
+</p>
+<pre><code>
+// <a href="source/javaextend.js">javaextend.js</a>
+
+var ArrayList = Java.type("java.util.ArrayList")
+var ArrayListExtender = Java.extend(ArrayList)
+var printSizeInvokedArrayList = new ArrayListExtender() {
+    size: function() { print("size invoked!"); }
+}

+</code></pre>
+<p>
+The reason you must use <code>Java.extend()</code> with concrete classes is that with concrete classes, there can be a 
+syntactic ambiguity if you just invoke their constructor. Consider this example:
+</p>
+<pre><code>
+var t = new java.lang.Thread({ run: function() { print("Hello!") } })
+</code></pre>
+<p>
+If we allowed subclassing of concrete classes with constructor syntax, Nashorn couldn't tell if you're creating a new 
+<code>Thread</code> and passing it a <code>Runnable</code> at this point, or you are subclassing <code>Thread</code> and
+passing it a new implementation for its own <code>run()</code> method.
+</p>
+<hr>
+<a name="jsimplementmultiple" id="jsimplementmultiple"></a>
+<h3>Implementing Multiple Interfaces</h3>
+<p>
+<code>Java.extend</code> can in fact take a list of multiple types. At most one of the types can be a class, and the rest must
+be interfaces (the class doesn't have to be the first in the list). You will get back an object that extends the class and 
+implements all the interfaces. (Obviously, if you only specify interfaces and no class, the object will extend <code>java.lang.Object</code>).
+<hr>
+<a name="classBoundImplementations" id="classBoundImplementations"></a>
+<h3>Class-Bound Implementations</h3>
+<p>
+The methods shown so far for extending Java classes and implementing interfaces &ndash; passing an implementation JavaScript object 
+or function to a constructor, or using <code>Java.extend</code> with <code>new</code> &ndash; all produce classes that take an
+extra JavaScript object parameter in their constructors that specifies the implementation. The implementation is therefore always bound
+to the actual instance being created with <code>new</code>, and not to the whole class. This has some advantages, for example in the
+memory footprint of the runtime, as Nashorn can just create a single "universal adapter" for every combination of types being implemented.
+In reality, the below code shows that different instantiations of, say, <code>Runnable</code> have the same class regardless of them having
+different JavaScript implementation objects:
+</p>
+<pre><code>
+var Runnable = java.lang.Runnable;
+var r1 = new Runnable(function() { print("I'm runnable 1!") })
+var r2 = new Runnable(function() { print("I'm runnable 2!") })
+r1.run()
+r2.run()
+print("We share the same class: " + (r1.class === r2.class))
+</code></pre>
+<p>
+prints:
+</p>
+<pre><code>
+I'm runnable 1!
+I'm runnable 2!
+We share the same class: true
+</code></pre>
+<p>
+Sometimes, however, you'll want to extend a Java class or implement an interface with implementation bound to the class, not to
+its instances. Such a need arises, for example, when you need to pass the class for instantiation to an external API; prime example
+of this is the JavaFX framework where you need to pass an Application class to the FX API and let it instantiate it.
+</p>
+<p>
+Fortunately, there's a solution for that: <code>Java.extend()</code> &ndash; aside from being able to take any number of type parameters
+denoting a class to extend and interfaces to implement &ndash; can also take one last argument that has to be a JavaScript object
+that serves as the implementation for the methods. In this case, <code>Java.extend()</code> will create a class that has the same
+constructors as the original class had, as they don't need to take an an extra implementation object parameter. The example below
+shows how you can create class-bound implementations, and shows that in this case, the implementation classes for different invocations
+are indeed different:
+</p>
+<pre><code>
+var RunnableImpl1 = Java.extend(java.lang.Runnable, function() { print("I'm runnable 1!") })
+var RunnableImpl2 = Java.extend(java.lang.Runnable, function() { print("I'm runnable 2!") })
+var r1 = new RunnableImpl1()
+var r2 = new RunnableImpl2()
+r1.run()
+r2.run()
+print("We share the same class: " + (r1.class === r2.class))
+</code></pre>
+<p>
+prints:
+</p>
+<pre><code>
+I'm runnable 1!
+I'm runnable 2!
+We share the same class: false
+</code></pre>
+<p>
+As you can see, the major difference here is that we moved the implementation object into the invocation of <code>Java.extend</code>
+from the constructor invocations &ndash; indeed the constructor invocations now don't even need to take an extra parameter! Since
+the implementations are bound to a class, the two classes obviously can't be the same, and we indeed see that the two runnables no
+longer share the same class &ndash; every invocation of <code>Java.extend()</code> with a class-specific implementation object triggers
+the creation of a new Java adapter class.
+</p>
+<p>
+Finally, the adapter classes with class-bound implementations can <i>still</i> take an additional constructor parameter to further
+override the behavior on a per-instance basis. Thus, you can even combine the two approaches: you can provide part of the implementation
+in a class-based JavaScript implementation object passed to <code>Java.extend</code>, and part in another object passed to the constructor.
+Whatever functions are provided by the constructor-passed object will override the functions in the class-bound object.
+</p>
+<pre><code>
+var RunnableImpl = Java.extend(java.lang.Runnable, function() { print("I'm runnable 1!") })
+var r1 = new RunnableImpl()
+var r2 = new RunnableImpl(function() { print("I'm runnable 2!") })
+r1.run()
+r2.run()
+print("We share the same class: " + (r1.class === r2.class))
+</code></pre>
+<p>
+prints:
+</p>
+<pre><code>
+I'm runnable 1!
+I'm runnable 2!
+We share the same class: true
+</code></pre>
+<hr>
+<a name="jsoverload" id="jsoverload"></a>
+<h3>Overload Resolution</h3>
+<p>Java methods can be overloaded by argument types. In Java,
+overload resolution occurs at compile time (performed by javac).
+When calling Java methods from Nashorn, the appropriate method will be
+selected based on the argument types at invocation time. You do not need
+to do anything special &ndash; the correct Java method overload variant 
+is selected based automatically. You still have the option of explicitly
+specifying a particular overload variant. Reasons for this include 
+either running into a genuine ambiguity with actual argument types, or 
+rarely reasons of performance &ndash; if you specify the actual overload
+then the engine doesn't have to perform resolution during invocation.
+Individual overloads of a Java methods are exposed as special properties
+with the name of the method followed with its signature in parentheses. 
+You can invoke them like this:</p>
+<pre><code>
+// <a href="source/overload.js">overload.js</a>
+
+var out = java.lang.System.out;
+
+// select a particular print function 
+out["println(Object)"]("hello");
+</code>
+</pre>
+<p>
+Note that you normally don't even have to use qualified class names in 
+the signatures as long as the unqualified name of the type is sufficient
+for uniquely identifying the signature. In practice this means that only
+in the extremely unlikely case that two overloads only differ in 
+parameter types that have identical unqualified names but come from 
+different packages would you need to use the fully qualified name of the
+class.
+</p>
+<hr>
+<a name="dataTypeMapping" id="dataTypeMapping"></a>
+<h3>Mapping of Data Types Between Java and JavaScript</h3>
+<p>
+We have previously shown some of the data type mappings between Java and JavaScript.
+We saw that arrays need to be explicitly converted. We have also shown that JavaScript functions
+are automatically converted to SAM types when passed as parameters to Java methods. Most other
+conversions work as you would expect.
+</p>
+<p>
+Every JavaScript object is also a <code>java.util.Map</code> so APIs receiving maps will receive them directly.
+</p>
+<p>
+When numbers are passed to a Java API, they will be converted to the expected target numeric type, either boxed or
+primitive, but if the target type is less specific, say <code>Number</code> or <code>Object</code>, you can only
+count on them being a <code>Number</code>, and have to test specifically for whether it's a boxed <code>Double</code>,
+<code>Integer</code>, <code>Long</code>, etc. &ndash; it can be any of these due to internal optimizations. Also, you 
+can pass any JavaScript value to a Java API expecting either a boxed or primitive number; the JavaScript specification's
+<code>ToNumber</code> conversion algorithm will be applied to the value.
+</p>
+<p>
+In a similar vein, if a Java method expects a <code>String</code> or a <code>Boolean</code>, the values will be
+converted using all conversions allowed by the JavaScript specification's <code>ToString</code> and <code>ToBoolean</code>
+conversions.
+</p>
+<p>
+Finally, a word of caution about strings. Due to internal performance optimizations of string operations, JavaScript strings are
+not always necessarily of type <code>java.lang.String</code>, but they will always be of type <code>java.lang.CharSequence</code>.
+If you pass them to a Java method that expects a <code>java.lang.String</code> parameter, then you will naturally receive a Java
+String, but if the signature of your method is more generic, i.e. it receives a <code>java.lang.Object</code> parameter, you can 
+end up with an object of private engine implementation class that implements <code>CharSequence</code> but is not a Java String.
+</p>

+<h2>Implementing Your Own Script Engine</h2>
+<p>We will not cover implementation of JSR-223 compliant script
+engines in detail. Minimally, you need to implement the
+<code>javax.script.ScriptEngine</code> and
+<code>javax.script.ScriptEngineFactory</code> interfaces. The
+abstract class <code>javax.script.AbstractScriptEngine</code>
+provides useful defaults for a few methods of the
+<code>ScriptEngine</code> interface.</p>
+<p>Before starting to implement a JSR-223 engine, you may want to
+check <a href="http://java.net/projects/Scripting">http://java.net/projects/Scripting</a>
+project. This project maintains JSR-223 implementations for many
+popular open source scripting languages.</p>

 <p>This new way of running tests is developer-centric. It assumes that you have built a JDK locally and want to test it. Running common test targets is simple, and more complex ad-hoc combination of tests is possible. The user interface is forgiving, and clearly report errors it cannot resolve.</p>
 <p>The main target <code>test</code> uses the jdk-image as the tested product. There is also an alternate target <code>exploded-test</code> that uses the exploded image instead. Not all tests will run successfully on the exploded image, but using this target can greatly improve rebuild times for certain workflows.</p>
 <p>Previously, <code>make test</code> was used to invoke an old system for running tests, and <code>make run-test</code> was used for the new test framework. For backward compatibility with scripts and muscle memory, <code>run-test</code> (and variants like <code>exploded-run-test</code> or <code>run-test-tier1</code>) are kept as aliases.</p>

 ## Notes for Specific Tests

 ### Docker Tests

-Docker tests with default parameters may fail on systems with glibc versions
-not compatible with the one used in the default docker image (e.g., Oracle
-Linux 7.6 for x86). For example, they pass on Ubuntu 16.04 but fail on Ubuntu
-18.04 if run like this on x86:

 ### Non-US locale

-If your locale is non-US, some tests are likely to fail. To work around this
-you can set the locale to US. On Unix platforms simply setting `LANG="en_US"`
-in the environment before running tests should work. On Windows, setting
-`JTREG="VM_OPTIONS=-Duser.language=en -Duser.country=US"` helps for most, but
-not all test cases.

 ### PKCS11 Tests

-It is highly recommended to use the latest NSS version when running PKCS11
-tests. Improper NSS version may lead to unexpected failures which are hard to
-diagnose. For example, sun/security/pkcs11/Secmod/AddTrustedCert.java may fail
-on Ubuntu 18.04 with the default NSS version in the system. To run these tests
-correctly, the system property `test.nss.lib.paths` is required on Ubuntu 18.04
-to specify the alternative NSS lib directories.

 ### Client UI Tests

 Some Client UI tests use key sequences which may be reserved by the operating
-system. Usually that causes the test failure. So it is highly recommended to
-disable system key shortcuts prior testing. The steps to access and disable
-system key shortcuts for various platforms are provided below.
+system. Usually that causes the test failure. So it is highly recommended to disable
+system key shortcuts prior testing. The steps to access and disable system key shortcuts
+for various platforms are provided below.

 #### MacOS
-
 Choose Apple menu; System Preferences, click Keyboard, then click Shortcuts;
 select or deselect desired shortcut.

-For example,
-test/jdk/javax/swing/TooltipManager/JMenuItemToolTipKeyBindingsTest/JMenuItemToolTipKeyBindingsTest.java
-fails on MacOS because it uses `CTRL + F1` key sequence to show or hide tooltip
-message but the key combination is reserved by the operating system. To run the
-test correctly the default global key shortcut should be disabled using the
-steps described above, and then deselect "Turn keyboard access on or off"
-option which is responsible for `CTRL + F1` combination.

Anton Tarasov	f86ae84567	IDEA-153474 let JDK detect Xft.dpi value on non-GTK Linux DEs Use the GTK method: https://developer.gnome.org/gobject/stable/gobject-The-Base-Object-Type.html#g-object-get to retrieve "gtk-xft-dpi" integer property of the X settings. Add the property to JDK's GtkEngine & gtk2-interface. Then read the property via GtkEngine from GTK LaF when "gnome.Xft/dpi" is undefined. It's assumed GTK LaF is forcedly installed.
