+
+## Getting Sources
+### macOS, Linux
+```
+git config --global core.autocrlf input
+git clone git@github.com:JetBrains/JetBrainsRuntime.git
+```
+
+### Windows
+<a name="sources-windows"></a>
+```
+git config --global core.autocrlf false
+git clone git@github.com:JetBrains/JetBrainsRuntime.git
+```
+
+## Configuring the Build Environment
+Here are quick per-platform instructions for those who can't wait to get started. 
+Please refer to [OpenJDK build docs](https://openjdk.java.net/groups/build/doc/building.html) for in-depth
+coverage of all the details.
+
+> **_TIP:_**  To get a preliminary report of what's missing, run `./configure` and check its output. 
+> It would usually have a meaningful advice on how to solve the problem.
+
+### Linux (Docker)
+Create a container:
+```
+$ cd jb/project/docker
+$ docker build .
+...
+Successfully built 942ea9900054
+```
+Run these commands in the new container:
+```
+$ docker run -v `pwd`../../../../:/JetBrainsRuntime -it 942ea9900054
+# cd /JetBrainsRuntime
+# sh ./configure
+# make images CONF=linux-x86_64-normal-server-release
+```
+
+### Ubuntu Linux
+Install the necessary tools, libraries, and headers with:
+```
+$ sudo apt-get install autoconf make build-essential libx11-dev libxext-dev libxrender-dev libxtst-dev \
+       libxt-dev libxrandr-dev libcups2-dev libfontconfig1-dev libasound2-dev
+```
+Get Java 17 (for instance, [Azul Zulu Builds of OpenJDK 17](https://www.azul.com/downloads/?version=java-17-ea&package=jdk)).
+
+Then run the following:
+```
+$ cd JetBrainsRuntime
+$ git checkout jbr-dev
+$ sh ./configure
+$ make images
+```
+This will build the release configuration under `./build/linux-x86_64-server-release/`.
+
+### Windows
+<a name="build-windows"></a>
+Install the following:
+* [Cygwin x64](http://www.cygwin.com/).
+  Required packages: `autoconf`, `binutils`, `cpio`, `diffutils`, `file`, `gawk`, `gcc-core`, `make`, `m4`, `unzip`, `zip`.  
+  Install those together with Cygwin.
+* [Visual Studio compiler toolset](https://visualstudio.microsoft.com/downloads/).
+  Install with the desktop development kit, which includes Windows SDK and compilers.
+  Visual Studio 2019 is supported by default.
+* Java 17 (for instance, [Azul Zulu Builds of OpenJDK 17](https://www.azul.com/downloads/?version=java-17-ea&os=windows&architecture=x86-64-bit&package=jdk).
+  If you have problems while configuring, read [Java tips on Cygwin](http://horstmann.com/articles/cygwin-tips.html).
+
+From the command line: 
+```
+"C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvarsall.bat" amd64
+"c:\Program_Files\cygwin64\bin\mintty.exe" /bin/bash -l
+```
+The first command sets up environment variables, the second starts a Cygwin shell with the proper environment.  
+
+In the Cygwin shell: 
+```
+$ cd JetBrainsRuntime
+$ git checkout jbr-dev
+$ bash configure --with-toolchain-version=2019
+$ make images
+```
+This will build the release configuration under `./build/windows-x86_64-server-release/`.
+
+### macOS
+Install the following:
+* Xcode command line developer tools and `autoconf` via [Homebrew](https://brew.sh/).
+* Java 17 (for instance, [Azul Zulu Builds of OpenJDK 17](https://www.azul.com/downloads/?version=java-17-ea&package=jdk)).
+
+From the command line:
+```
+$ cd JetBrainsRuntime
+$ git checkout jbr-dev
+$ sh ./configure
+$ make images
+```
+This will build the release configuration under `./build/macosx-x86_64-server-release/`.
+
+## Developing
+You can use  [CLion](https://www.jetbrains.com/clion/) to develop native parts of the JetBrains Runtime and
+[IntelliJ IDEA](https://www.jetbrains.com/idea/) for the parts written in Java.
+Both require projects to be created.
+
+### CLion
+Run
+```
+$ make compile-commands
+```
+in the git root and open the resulting `build/.../compile_commands.json` file as a project.
+Then use `Tools | Compilation Database | Change Project Root` to point to git root of this repository.
+
+See also this detailed step-by-step tutorial for all platforms:
+[How to develop OpenJDK with CLion](https://blog.jetbrains.com/clion/2020/03/openjdk-with-clion/).
+
+### IDEA
+Run
+```
+$ sh ./bin/idea.sh
+```
+in the git root to generate project files (add `--help` for options). If you have multiple
+configurations (for example, `release` and `fastdebug`), supply the `--conf <conf_name>` argument.
+Then open the git root directory as a project in IDEA.

-## Signing
-
-### macOS
-
-Modern versions of macOS require applications to be signed and notarizied before
-distribution. See Apple's documentation for more background on what this means
-and how it works. To help support this, the JDK build can be configured to
-automatically sign all native binaries, and the JDK bundle, with all the options
-needed for successful notarization, as well as all the entitlements required by
-the JDK. To enable `hardened` signing, use configure parameter
-`--with-macosx-codesign=hardened` and configure the signing identity you wish to
-use with `--with-macosx-codesign-identity=<identity>`. The identity refers to a
-signing identity from Apple that needs to be preinstalled on the build host.
-
-When not signing for distribution with the hardened option, the JDK build will
-still attempt to perform `adhoc` signing to add the special entitlement
-`com.apple.security.get-task-allow` to each binary. This entitlement is required
-to be able to dump core files from a process. Note that adding this entitlement
-makes the build invalid for notarization, so it is only added when signing in
-`debug` mode. To explicitly enable this kind of adhoc signing, use configure
-parameter `--with-macosx-codesign=debug`. It will be enabled by default in most
-cases.
-
-It's also possible to completely disable any explicit codesign operations done
-by the JDK build using the configure parameter `--without-macosx-codesign`.
-The exact behavior then depends on the architecture. For macOS on x64, it (at
-least at the time of this writing) results in completely unsigned binaries that
-should still work fine for development and debugging purposes. On aarch64, the
-Xcode linker will apply a default "adhoc" signing, without any entitlements.
-Such a build does not allow dumping core files.
-
-The default mode "auto" will try for `hardened` signing if the debug level is
-`release` and either the default identity or the specified identity is valid.
-If hardened isn't possible, then `debug` signing is chosen if it works. If
-nothing works, the codesign build step is disabled.

-An absolute prerequisite for building reproducible is to speficy a fixed build
-time, since time stamps are embedded in many file formats. This is done by
-setting the `SOURCE_DATE_EPOCH` environment variable, which is an [industry
-standard]( https://reproducible-builds.org/docs/source-date-epoch/), that many
-tools, such as gcc, recognize, and use in place of the current time when
-generating output.
+  * Turn on build system support for reproducible builds
 
-To generate reproducible builds, you must set `SOURCE_DATE_EPOCH` before running
-`configure`. The value in `SOURCE_DATE_EPOCH` will be stored in the
-configuration, and used by `make`. Setting `SOURCE_DATE_EPOCH` before running
-`make` will have no effect on the build.
+Add the flag `--enable-reproducible-build` to your `configure` command line.
+This will turn on support for reproducible builds where it could otherwise be
+lacking.
 
-You must also make sure your build does not rely on `configure`'s default adhoc
-version strings. Default adhoc version strings `OPT` segment include user name
-and source directory. You can either override just the `OPT` segment using
+  * Do not rely on `configure`'s default adhoc version strings
+
+Default adhoc version strings OPT segment include user name, source directory
+and timestamp. You can either override just the OPT segment using
 `--with-version-opt=<any fixed string>`, or you can specify the entire version
 string using `--with-version-string=<your version>`.
 
-This is a typical example of how to build the JDK in a reproducible way:
+  * Specify how the build sets `SOURCE_DATE_EPOCH`
 
-```
-export SOURCE_DATE_EPOCH=946684800
-bash configure --with-version-opt=adhoc
-make
-```
+The JDK build system will set the `SOURCE_DATE_EPOCH` environment variable
+during building, depending on the value of the `--with-source-date` option for
+`configure`. The default value is `updated`, which means that
+`SOURCE_DATE_EPOCH` will be set to the current time each time you are running
+`make`.
 
-Note that regardless if you specify a source date for `configure` or not, the
-JDK build system will set `SOURCE_DATE_EPOCH` for all build tools when building.
-If `--with-source-date` has the value `current` (which is the default unless
-`SOURCE_DATE_EPOCH` is found by in the environment by `configure`), the source
-date value will be determined at configure time.
+The [`SOURCE_DATE_EPOCH` environment variable](
+https://reproducible-builds.org/docs/source-date-epoch/) is an industry
+standard, that many tools, such as gcc, recognize, and use in place of the
+current time when generating output.
 
-There are several aspects of reproducible builds that can be individually
-adjusted by `configure` arguments. If any of these are given, they will override
-the value derived from `SOURCE_DATE_EPOCH`. These arguments are:
+For reproducible builds, you need to set this to a fixed value. You can use the
+special value `version` which will use the nominal release date for the current
+JDK version, or a value describing a date, either an epoch based timestamp as an
+integer, or a valid ISO-8601 date.
 
- * `--with-source-date`
+**Hint:** If your build environment already sets `SOURCE_DATE_EPOCH`, you can
+propagate this using `--with-source-date=$SOURCE_DATE_EPOCH`.
 
-    This option controls how the JDK build sets `SOURCE_DATE_EPOCH` when
-    building. It can be set to a value describing a date, either an epoch based
-    timestamp as an integer, or a valid ISO-8601 date.
+  * Specify a hotspot build time
 
-    It can also be set to one of the special values `current`, `updated` or
-    `version`. `current` means that the time of running `configure` will be
-    used. `version` will use the nominal release date for the current JDK
-    version. `updated`, which means that `SOURCE_DATE_EPOCH` will be set to the
-    current time each time you are running `make`. All choices, except for
-    `updated`, will set a fixed value for the source date timestamp.
+Set a fixed hotspot build time. This will be included in the hotspot library
+(`libjvm.so` or `jvm.dll`) and defaults to the current time when building
+hotspot. Use `--with-hotspot-build-time=<any fixed string>` for reproducible
+builds. It's a string so you don't need to format it specifically, so e.g. `n/a`
+will do. Another solution is to use the `SOURCE_DATE_EPOCH` variable, e.g.
+`--with-hotspot-build-time=$(date --date=@$SOURCE_DATE_EPOCH)`.
 
-    When `SOURCE_DATE_EPOCH` is set, the default value for `--with-source-date`
-    will be the value given by `SOURCE_DATE_EPOCH`. Otherwise, the default value
-    is `current`.
+  * Copyright year
 
- * `--with-hotspot-build-time`
-
-    This option controls the build time string that will be included in the
-    hotspot library (`libjvm.so` or `jvm.dll`). When the source date is fixed
-    (e.g. by setting `SOURCE_DATE_EPOCH`), the default value for
-    `--with-hotspot-build-time` will be an ISO 8601 representation of that time
-    stamp. Otherwise the default value will be the current time when building
-    hotspot.
-
- * `--with-copyright-year`
-
-    This option controls the copyright year in some generated text files. When
-    the source date is fixed (e.g. by setting `SOURCE_DATE_EPOCH`), the default
-    value for `--with-copyright-year` will be the year of that time stamp.
-    Otherwise the default is the current year at the time of running configure.
-    This can be overridden by `--with-copyright-year=<year>`.
-
- * `--enable-reproducible-build`
-
-    This option controls some additional behavior needed to make the build
-    reproducible. When the source date is fixed (e.g. by setting
-    `SOURCE_DATE_EPOCH`), this flag will be turned on by default. Otherwise, the
-    value is determined by heuristics. If it is explicitly turned off, the build
-    might not be reproducible.
+The copyright year in some generated text files are normally set to the current
+year. This can be overridden by `--with-copyright-year=<year>`. For fully
+reproducible builds, this needs to be set to a fixed value.

 <h2 id="good-test-properties">Good test properties</h2>
 <h3 id="lightness">Lightness</h3>
 <p>Use the most lightweight type of tests.</p>
-<p>In Hotspot, there are 3 different types of tests regarding their
-dependency on a JVM, each next level is slower than previous</p>
+<p>In Hotspot, there are 3 different types of tests regarding their dependency on a JVM, each next level is slower than previous</p>
 <ul>
 <li><p><code>TEST</code> : a test does not depend on a JVM</p></li>
-<li><p><code>TEST_VM</code> : a test does depend on an initialized JVM,
-but are supposed not to break a JVM, i.e. leave it in a workable
-state.</p></li>
-<li><p><code>TEST_OTHER_VM</code> : a test depends on a JVM and requires

+<li><p><code>TEST_OTHER_VM</code> : a test depends on a JVM and requires a freshly initialized JVM or leaves a JVM in non-workable state</p></li>
 </ul>
 <h3 id="isolation">Isolation</h3>
-<p>Tests have to be isolated: not to have visible side-effects,
-influences on other tests results.</p>
-<p>Results of one test should not depend on test execution order, other
-tests, otherwise it is becoming almost impossible to find out why a test
-failed. Due to hotspot-specific, it is not so easy to get a full
-isolation, e.g. we share an initialized JVM between all
-<code>TEST_VM</code> tests, so if your test changes JVM's state too
-drastically and does not change it back, you had better consider
-<code>TEST_OTHER_VM</code>.</p>
-<h3 id="atomicity-and-self-containment">Atomicity and
-self-containment</h3>
-<p>Tests should be <em>atomic</em> and <em>self-contained</em> at the
-same time.</p>
-<p>One test should check a particular part of a class, subsystem,
-functionality, etc. Then it is quite easy to determine what parts of a
-product are broken basing on test failures. On the other hand, a test
-should test that part more-or-less entirely, because when one sees a
-test <code>FooTest::bar</code>, they assume all aspects of bar from
-<code>Foo</code> are tested.</p>
-<p>However, it is impossible to cover all aspects even of a method, not
-to mention a subsystem. In such cases, it is recommended to have several
-tests, one for each aspect of a thing under test. For example one test
-to tests how <code>Foo::bar</code> works if an argument is
-<code>null</code>, another test to test how it works if an argument is
-acceptable but <code>Foo</code> is not in the right state to accept it
-and so on. This helps not only to make tests atomic, self-contained but
-also makes test name self-descriptive (discussed in more details in <a
-href="#test-names">Test names</a>).</p>

 <h3 id="repeatability">Repeatability</h3>
 <p>Tests have to be repeatable.</p>
-<p>Reproducibility is very crucial for a test. No one likes sporadic
-test failures, they are hard to investigate, fix and verify a fix.</p>
-<p>In some cases, it is quite hard to write a 100% repeatable test,
-since besides a test there can be other moving parts, e.g. in case of
-<code>TEST_VM</code> there are several concurrently running threads.
-Despite this, we should try to make a test as reproducible as
-possible.</p>

 <h3 id="informativeness">Informativeness</h3>
-<p>In case of a failure, a test should be as <em>informative</em> as
-possible.</p>
-<p>Having more information about a test failure than just compared
-values can be very useful for failure troubleshooting, it can reduce or
-even completely eliminate debugging hours. This is even more important
-in case of not 100% reproducible failures.</p>
-<p>Achieving this property, one can easily make a test too verbose, so
-it will be really hard to find useful information in the ocean of
-useless information. Hence they should not only think about how to
-provide <a href="#error-messages">good information</a>, but also <a
-href="#uncluttered-output">when to do it</a>.</p>

 <h3 id="testing-instead-of-visiting">Testing instead of visiting</h3>
 <p>Tests should <em>test</em>.</p>
-<p>It is not enough just to "visit" some code, a test should check that
-code does that it has to do, compare return values with expected values,
-check that desired side effects are done, and undesired are not, and so
-on. In other words, a test should contain at least one GoogleTest
-assertion and do not rely on JVM asserts.</p>
-<p>Generally speaking to write a good test, one should create a model of
-the system under tests, a model of possible bugs (or bugs which one
-wants to find) and design tests using those models.</p>

 <h3 id="nearness">Nearness</h3>
 <p>Prefer having checks inside test code.</p>
-<p>Not only does having test logic outside, e.g. verification method,
-depending on asserts in product code contradict with several items above
-but also decreases test’s readability and stability. It is much easier
-to understand that a test is testing when all testing logic is located
-inside a test or nearby in shared test libraries. As a rule of thumb,
-the closer a check to a test, the better.</p>

 <h2 id="asserts">Asserts</h2>
 <h3 id="several-checks">Several checks</h3>
 <p>Prefer <code>EXPECT</code> over <code>ASSERT</code> if possible.</p>
-<p>This is related to the <a href="#informativeness">informativeness</a>
-property of tests, information for other checks can help to better
-localize a defect’s root-cause. One should use <code>ASSERT</code> if it
-is impossible to continue test execution or if it does not make much
-sense. Later in the text, <code>EXPECT</code> forms will be used to
-refer to both <code>ASSERT/EXPECT</code>.</p>
-<p>When it is possible to make several different checks, but impossible
-to continue test execution if at least one check fails, you can use
-<code>::testing::Test::HasNonfatalFailure()</code> function. The
-recommended way to express that is
-<code>ASSERT_FALSE(::testing::Test::HasNonfatalFailure())</code>.
-Besides making it clear why a test is aborted, it also allows you to
-provide more information about a failure.</p>
-<h3 id="first-parameter-is-expected-value">First parameter is expected
-value</h3>
-<p>In all equality assertions, expected values should be passed as the
-first parameter.</p>
-<p>This convention is adopted by GoogleTest, and there is a slight
-difference in how GoogleTest treats parameters, the most important one
-is <code>null</code> detection. Due to different reasons,
-<code>null</code> detection is enabled only for the first parameter,
-that is to said <code>EXPECT_EQ(NULL, object)</code> checks that object
-is <code>null</code>, while <code>EXPECT_EQ(object, NULL)</code> checks
-that object equals to <code>NULL</code>, GoogleTest is very strict
-regarding types of compared values so the latter will generates a

 <h3 id="floating-point-comparison">Floating-point comparison</h3>
-<p>Use floating-point special macros to compare
-<code>float/double</code> values.</p>
-<p>Because of floating-point number representations and round-off
-errors, regular equality comparison will not return true in most cases.
-There are special <code>EXPECT_FLOAT_EQ/EXPECT_DOUBLE_EQ</code>
-assertions which check that the distance between compared values is not
-more than 4 ULPs, there is also <code>EXPECT_NEAR(v1, v2, eps)</code>
-which checks that the absolute value of the difference between
-<code>v1</code> and <code>v2</code> is not greater than
-<code>eps</code>.</p>

-<p><code>EXPECT_EQ</code> just compares pointers’ values, which is
-hardly what one wants comparing C strings. GoogleTest provides
-<code>EXPECT_STREQ</code> and <code>EXPECT_STRNE</code> macros to

 <h3 id="error-messages">Error messages</h3>
 <p>Provide informative, but not too verbose error messages.</p>
-<p>All GoogleTest asserts print compared expressions and their values,
-so there is no need to have them in error messages. Asserts print only
-compared values, they do not print any of interim variables, e.g.
-<code>ASSERT_TRUE((val1 == val2 &amp;&amp; isFail(foo(8)) || i == 18)</code>
-prints only one value. If you use some complex predicates, please
-consider <code>EXPECT_PRED*</code> or <code>EXPECT_FORMAT_PRED</code>
-assertions family, they check that a predicate returns true/success and
-print out all parameters values.</p>
-<p>However in some cases, default information is not enough, a commonly
-used example is an assert inside a loop, GoogleTest will not print
-iteration values (unless it is an assert's parameter). Other
-demonstrative examples are printing error code and a corresponding error
-message; printing internal states which might have an impact on results.
-One should add this information to assert message using
-<code>&lt;&lt;</code> operator.</p>

 <h3 id="uncluttered-output">Uncluttered output</h3>
 <p>Print information only if it is needed.</p>
-<p>Too verbose tests which print all information even if they pass are
-very bad practice. They just pollute output, so it becomes harder to
-find useful information. In order not print information till it is
-really needed, one should consider saving it to a temporary buffer and

 <h3 id="failures-propagation">Failures propagation</h3>
-<p>Wrap a subroutine call into <code>EXPECT_NO_FATAL_FAILURE</code>
-macro to propagate failures.</p>
-<p><code>ASSERT</code> and <code>FAIL</code> abort only the current
-function, so if you have them in a subroutine, a test will not be
-aborted after the subroutine even if <code>ASSERT</code> or
-<code>FAIL</code> fails. You should call such subroutines in
-<code>ASSERT_NO_FATAL_FAILURE</code> macro to propagate fatal failures
-and abort a test. <code>(EXPECT|ASSERT)_NO_FATAL_FAILURE</code> can also
-be used to provide more information.</p>
-<p>Due to obvious reasons, there are no
-<code>(EXPECT|ASSERT)_NO_NONFATAL_FAILURE</code> macros. However, if you
-need to check if a subroutine generated a nonfatal failure (failed an
-<code>EXPECT</code>), you can use
-<code>::testing::Test::HasNonfatalFailure</code> function, or
-<code>::testing::Test::HasFailure</code> function to check if a
-subroutine generated any failures, see <a href="#several-checks">Several

 <h2 id="naming-and-grouping">Naming and Grouping</h2>
 <h3 id="test-group-names">Test group names</h3>
-<p>Test group names should be in CamelCase, start and end with a letter.
-A test group should be named after tested class, functionality,
-subsystem, etc.</p>
-<p>This naming scheme helps to find tests, filter them and simplifies
-test failure analysis. For example, class <code>Foo</code> - test group
-<code>Foo</code>, compiler logging subsystem - test group
-<code>CompilerLogging</code>, G1 GC — test group <code>G1GC</code>, and
-so forth.</p>

 <h3 id="test-names">Test names</h3>
-<p>Test names should be in small_snake_case, start and end with a

-<p>Such naming makes tests self-descriptive and helps a lot during the
-whole test life cycle. It is easy to do test planning, test inventory,
-to see what things are not tested, to review tests, to analyze test
-failures, to evolve a test, etc. For example
-<code>foo_return_0_if_name_is_null</code> is better than
-<code>foo_sanity</code> or <code>foo_basic</code> or just
-<code>foo</code>,
-<code>humongous_objects_can_not_be_moved_by_young_gc</code> is better
-than <code>ho_young_gc</code>.</p>
-<p>Actually using underscore is against GoogleTest project convention,
-because it can lead to illegal identifiers, however, this is too strict.
-Restricting usage of underscore for test names only and prohibiting test
-name starts or ends with an underscore are enough to be safe.</p>
+<p>Test names should be in small_snake_case, start and end with a letter. A test name should reflect that a test checks.</p>
+<p>Such naming makes tests self-descriptive and helps a lot during the whole test life cycle. It is easy to do test planning, test inventory, to see what things are not tested, to review tests, to analyze test failures, to evolve a test, etc. For example <code>foo_return_0_if_name_is_null</code> is better than <code>foo_sanity</code> or <code>foo_basic</code> or just <code>foo</code>, <code>humongous_objects_can_not_be_moved_by_young_gc</code> is better than <code>ho_young_gc</code>.</p>
+<p>Actually using underscore is against GoogleTest project convention, because it can lead to illegal identifiers, however, this is too strict. Restricting usage of underscore for test names only and prohibiting test name starts or ends with an underscore are enough to be safe.</p>

-<h2 id="overview">Overview</h2>
-<p>The bulk of JDK tests use <a
-href="https://openjdk.org/jtreg/">jtreg</a>, a regression test framework
-and test runner built for the JDK's specific needs. Other test
-frameworks are also used. The different test frameworks can be executed
-directly, but there is also a set of make targets intended to simplify
-the interface, and figure out how to run your tests for you.</p>
-<h2 id="running-tests-locally-with-make-test">Running tests locally with
-<code>make test</code></h2>
-<p>This is the easiest way to get started. Assuming you've built the JDK
-locally, execute:</p>
-<pre><code>$ make test</code></pre>
-<p>This will run a default set of tests against the JDK, and present you
-with the results. <code>make test</code> is part of a family of
-test-related make targets which simplify running tests, because they
-invoke the various test frameworks for you. The "make test framework" is
-simple to start with, but more complex ad-hoc combination of tests is
-also possible. You can always invoke the test frameworks directly if you
-want even more control.</p>
+<h2 id="using-make-test-the-run-test-framework">Using &quot;make test&quot; (the run-test framework)</h2>
+<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>
 <p>Some example command-lines:</p>
 <pre><code>$ make test-tier1
 $ make test-jdk_lang JTREG=&quot;JOBS=8&quot;

-<p>"tier1" and "tier2" refer to tiered testing, see further down. "TEST"

-frameworks, and if the test isn't present in one, it tries the next one.

 <h3 id="configuration">Configuration</h3>
-<p>To be able to run JTReg tests, <code>configure</code> needs to know
-where to find the JTReg test framework. If it is not picked up
-automatically by configure, use the
-<code>--with-jtreg=&lt;path to jtreg home&gt;</code> option to point to
-the JTReg framework. Note that this option should point to the JTReg
-home, i.e. the top directory, containing <code>lib/jtreg.jar</code> etc.
-(An alternative is to set the <code>JT_HOME</code> environment variable
-to point to the JTReg home before running <code>configure</code>.)</p>
-<p>To be able to run microbenchmarks, <code>configure</code> needs to
-know where to find the JMH dependency. Use
-<code>--with-jmh=&lt;path to JMH jars&gt;</code> to point to a directory
-containing the core JMH and transitive dependencies. The recommended
-dependencies can be retrieved by running
-<code>sh make/devkit/createJMHBundle.sh</code>, after which
-<code>--with-jmh=build/jmh/jars</code> should work.</p>
-<p>When tests fail or timeout, jtreg runs its failure handler to capture
-necessary data from the system where the test was run. This data can
-then be used to analyze the test failures. Collecting this data involves
-running various commands (which are listed in files residing in
-<code>test/failure_handler/src/share/conf</code>) and some of these
-commands use <code>sudo</code>. If the system's <code>sudoers</code>
-file isn't configured to allow running these commands, then it can
-result in password being prompted during the failure handler execution.
-Typically, when running locally, collecting this additional data isn't
-always necessary. To disable running the failure handler, use
-<code>--enable-jtreg-failure-handler=no</code> when running
-<code>configure</code>. If, however, you want to let the failure handler
-to run and don't want to be prompted for sudo password, then you can
-configure your <code>sudoers</code> file appropriately. Please read the
-necessary documentation of your operating system to see how to do that;
-here we only show one possible way of doing that - edit the
-<code>/etc/sudoers.d/sudoers</code> file to include the following
-line:</p>
-<pre><code>johndoe ALL=(ALL) NOPASSWD: /sbin/dmesg</code></pre>
-<p>This line configures <code>sudo</code> to <em>not</em> prompt for
-password for the <code>/sbin/dmesg</code> command (this is one of the
-commands that is listed in the files at
-<code>test/failure_handler/src/share/conf</code>), for the user
-<code>johndoe</code>. Here <code>johndoe</code> is the user account
-under which the jtreg tests are run. Replace the username with a
-relevant user account of your system.</p>
+<p>To be able to run JTReg tests, <code>configure</code> needs to know where to find the JTReg test framework. If it is not picked up automatically by configure, use the <code>--with-jtreg=&lt;path to jtreg home&gt;</code> option to point to the JTReg framework. Note that this option should point to the JTReg home, i.e. the top directory, containing <code>lib/jtreg.jar</code> etc. (An alternative is to set the <code>JT_HOME</code> environment variable to point to the JTReg home before running <code>configure</code>.)</p>

 <h2 id="test-selection">Test selection</h2>
-<p>All functionality is available using the <code>test</code> make
-target. In this use case, the test or tests to be executed is controlled
-using the <code>TEST</code> variable. To speed up subsequent test runs
-with no source code changes, <code>test-only</code> can be used instead,
-which do not depend on the source and test image build.</p>
-<p>For some common top-level tests, direct make targets have been
-generated. This includes all JTReg test groups, the hotspot gtest, and
-custom tests (if present). This means that <code>make test-tier1</code>
-is equivalent to <code>make test TEST="tier1"</code>, but the latter is
-more tab-completion friendly. For more complex test runs, the
-<code>test TEST="x"</code> solution needs to be used.</p>
-<p>The test specifications given in <code>TEST</code> is parsed into
-fully qualified test descriptors, which clearly and unambigously show
-which tests will be run. As an example, <code>:tier1</code> will expand
-to
-<code>jtreg:$(TOPDIR)/test/hotspot/jtreg:tier1 jtreg:$(TOPDIR)/test/jdk:tier1 jtreg:$(TOPDIR)/test/langtools:tier1 jtreg:$(TOPDIR)/test/nashorn:tier1 jtreg:$(TOPDIR)/test/jaxp:tier1</code>.
-You can always submit a list of fully qualified test descriptors in the
-<code>TEST</code> variable if you want to shortcut the parser.</p>

 <h3 id="common-test-groups">Common Test Groups</h3>
-<p>Ideally, all tests are run for every change but this may not be
-practical due to the limited testing resources, the scope of the change,
-etc.</p>
-<p>The source tree currently defines a few common test groups in the
-relevant <code>TEST.groups</code> files. There are test groups that
-cover a specific component, for example <code>hotspot_gc</code>. It is a
-good idea to look into <code>TEST.groups</code> files to get a sense
-what tests are relevant to a particular JDK component.</p>
-<p>Component-specific tests may miss some unintended consequences of a
-change, so other tests should also be run. Again, it might be
-impractical to run all tests, and therefore <em>tiered</em> test groups
-exist. Tiered test groups are not component-specific, but rather cover
-the significant parts of the entire JDK.</p>
-<p>Multiple tiers allow balancing test coverage and testing costs. Lower
-test tiers are supposed to contain the simpler, quicker and more stable
-tests. Higher tiers are supposed to contain progressively more thorough,
-slower, and sometimes less stable tests, or the tests that require
-special configuration.</p>
-<p>Contributors are expected to run the tests for the areas that are
-changed, and the first N tiers they can afford to run, but at least
-tier1.</p>

 <p>A brief description of the tiered test groups:</p>
 <ul>
-<li><p><code>tier1</code>: This is the lowest test tier. Multiple
-developers run these tests every day. Because of the widespread use, the
-tests in <code>tier1</code> are carefully selected and optimized to run
-fast, and to run in the most stable manner. The test failures in
-<code>tier1</code> are usually followed up on quickly, either with
-fixes, or adding relevant tests to problem list. GitHub Actions
-workflows, if enabled, run <code>tier1</code> tests.</p></li>
-<li><p><code>tier2</code>: This test group covers even more ground.
-These contain, among other things, tests that either run for too long to
-be at <code>tier1</code>, or may require special configuration, or tests
-that are less stable, or cover the broader range of non-core JVM and JDK
-features/components(for example, XML).</p></li>
-<li><p><code>tier3</code>: This test group includes more stressful
-tests, the tests for corner cases not covered by previous tiers, plus
-the tests that require GUIs. As such, this suite should either be run
-with low concurrency (<code>TEST_JOBS=1</code>), or without headful
-tests(<code>JTREG_KEYWORDS=\!headful</code>), or both.</p></li>
-<li><p><code>tier4</code>: This test group includes every other test not
-covered by previous tiers. It includes, for example,
-<code>vmTestbase</code> suites for Hotspot, which run for many hours
-even on large machines. It also runs GUI tests, so the same
-<code>TEST_JOBS</code> and <code>JTREG_KEYWORDS</code> caveats
-apply.</p></li>

 <h3 id="jtreg">JTReg</h3>
-<p>JTReg tests can be selected either by picking a JTReg test group, or
-a selection of files or directories containing JTReg tests.
-Documentation can be found at <a
-href="https://openjdk.org/jtreg/">https://openjdk.org/jtreg/</a>, note
-especially the extensive <a
-href="https://openjdk.org/jtreg/faq.html">FAQ</a>.</p>
-<p>JTReg test groups can be specified either without a test root, e.g.
-<code>:tier1</code> (or <code>tier1</code>, the initial colon is
-optional), or with, e.g. <code>hotspot:tier1</code>,
-<code>test/jdk:jdk_util</code> or
-<code>$(TOPDIR)/test/hotspot/jtreg:hotspot_all</code>. The test root can
-be specified either as an absolute path, or a path relative to the JDK
-top directory, or the <code>test</code> directory. For simplicity, the
-hotspot JTReg test root, which really is <code>hotspot/jtreg</code> can
-be abbreviated as just <code>hotspot</code>.</p>
-<p>When specified without a test root, all matching groups from all test
-roots will be added. Otherwise, only the group from the specified test
-root will be added.</p>
-<p>Individual JTReg tests or directories containing JTReg tests can also
-be specified, like
-<code>test/hotspot/jtreg/native_sanity/JniVersion.java</code> or
-<code>hotspot/jtreg/native_sanity</code>. Just like for test root
-selection, you can either specify an absolute path (which can even point
-to JTReg tests outside the source tree), or a path relative to either
-the JDK top directory or the <code>test</code> directory.
-<code>hotspot</code> can be used as an alias for
-<code>hotspot/jtreg</code> here as well.</p>
-<p>As long as the test groups or test paths can be uniquely resolved,
-you do not need to enter the <code>jtreg:</code> prefix. If this is not
-possible, or if you want to use a fully qualified test descriptor, add
-<code>jtreg:</code>, e.g.
-<code>jtreg:test/hotspot/jtreg/native_sanity</code>.</p>

 <h3 id="gtest">Gtest</h3>
-<p><strong>Note:</strong> To be able to run the Gtest suite, you need to
-configure your build to be able to find a proper version of the gtest
-source. For details, see the section <a
-href="building.html#running-tests">"Running Tests" in the build
-documentation</a>.</p>
-<p>Since the Hotspot Gtest suite is so quick, the default is to run all
-tests. This is specified by just <code>gtest</code>, or as a fully
-qualified test descriptor <code>gtest:all</code>.</p>
-<p>If you want, you can single out an individual test or a group of
-tests, for instance <code>gtest:LogDecorations</code> or
-<code>gtest:LogDecorations.level_test_vm</code>. This can be
-particularly useful if you want to run a shaky test repeatedly.</p>
-<p>For Gtest, there is a separate test suite for each JVM variant. The
-JVM variant is defined by adding <code>/&lt;variant&gt;</code> to the
-test descriptor, e.g. <code>gtest:Log/client</code>. If you specify no
-variant, gtest will run once for each JVM variant present (e.g. server,
-client). So if you only have the server JVM present, then
-<code>gtest:all</code> will be equivalent to
-<code>gtest:all/server</code>.</p>

-<p>Which microbenchmarks to run is selected using a regular expression
-following the <code>micro:</code> test descriptor, e.g.,
-<code>micro:java.lang.reflect</code>. This delegates the test selection
-to JMH, meaning package name, class name and even benchmark method names
-can be used to select tests.</p>
-<p>Using special characters like <code>|</code> in the regular
-expression is possible, but needs to be escaped multiple times:
-<code>micro:ArrayCopy\\\\\|reflect</code>.</p>

 % Testing the JDK
 
-## Overview
+## Using "make test" (the run-test framework)
 
-The bulk of JDK tests use [jtreg](https://openjdk.org/jtreg/), a regression
-test framework and test runner built for the JDK's specific needs. Other test
-frameworks are also used. The different test frameworks can be executed
-directly, but there is also a set of make targets intended to simplify the
-interface, and figure out how to run your tests for you.
+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.
 
-## Running tests locally with `make test`
+The main target `test` uses the jdk-image as the tested product. There is
+also an alternate target `exploded-test` 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.
 
-This is the easiest way to get started. Assuming you've built the JDK locally,
-execute:
-
-    $ make test
-
-This will run a default set of tests against the JDK, and present you with the
-results. `make test` is part of a family of test-related make targets which
-simplify running tests, because they invoke the various test frameworks for
-you. The "make test framework" is simple to start with, but more complex
-ad-hoc combination of tests is also possible. You can always invoke the test
-frameworks directly if you want even more control.
+Previously, `make test` was used to invoke an old system for running tests, and
+`make run-test` was used for the new test framework. For backward compatibility
+with scripts and muscle memory, `run-test` (and variants like
+`exploded-run-test` or `run-test-tier1`) are kept as aliases.

 A brief description of the tiered test groups:
 
-- `tier1`: This is the lowest test tier. Multiple developers run these tests
-  every day. Because of the widespread use, the tests in `tier1` are
-  carefully selected and optimized to run fast, and to run in the most stable
-  manner. The test failures in `tier1` are usually followed up on quickly,
-  either with fixes, or adding relevant tests to problem list. GitHub Actions
-  workflows, if enabled, run `tier1` tests.

-  such, this suite should either be run with low concurrency
-  (`TEST_JOBS=1`), or without headful tests(`JTREG_KEYWORDS=\!headful`), or
