+# Welcome to OpenJDK 11 Updates!
+
+The JDK 11 Updates project uses two GitHub repositories.
+Updates are continuously developed in the repository [jdk11u-dev](https://github.com/openjdk/jdk11u-dev). This is the repository usually targeted by contributors.
+The [jdk11u](https://github.com/openjdk/jdk11u) repository is used for rampdown of the update releases of jdk11u and only accepts critical changes that must make the next release during rampdown. (You probably do not want to target jdk11u).
+
+For more OpenJDK 11 updates specific information such as timelines and contribution guidelines see the [project wiki page](https://wiki.openjdk.org/display/JDKUpdates/JDK11u).
+
+
+For build instructions please see the
+[online documentation](https://openjdk.java.net/groups/build/doc/building.html),
+or either of these files:
+
+- [doc/building.html](doc/building.html) (html version)
+- [doc/building.md](doc/building.md) (markdown version)
+
+See <https://openjdk.java.net/> for more information about
+the OpenJDK Community and the JDK.

-<p>Windows is the only non-POSIX OS supported by the JDK, and as such, requires some extra care. A POSIX support layer is required to build on Windows. Currently, the only supported such layer is Cygwin.

This rule also applies to input to the build system, e.g. in arguments to <code>configure</code>. So, use <code>--with-msvcr-dll=/cygdrive/c/msvcr100.dll</code> rather than <code>--with-msvcr-dll=c:\msvcr100.dll</code>.

+<h2 id="signing">Signing</h2>
+<h3 id="macos-1">macOS</h3>
+<p>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 <code>hardened</code> signing, use configure parameter <code>--with-macosx-codesign=hardened</code> and configure the signing identity you wish to use with <code>--with-macosx-codesign-identity=&lt;identity&gt;</code>. The identity refers to a signing identity from Apple that needs to be preinstalled on the build host.</p>
+<p>When not signing for distribution with the hardened option, the JDK build will still attempt to perform <code>adhoc</code> signing to add the special entitlement <code>com.apple.security.get-task-allow</code> 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 <code>debug</code> mode. To explicitly enable this kind of adhoc signing, use configure parameter <code>--with-macosx-codesign=debug</code>. It will be enabled by default in most cases.</p>
+<p>It's also possible to completely disable any explicit codesign operations done by the JDK build using the configure parameter <code>--without-macosx-codesign</code>. 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 &quot;adhoc&quot; signing, without any entitlements. Such a build does not allow dumping core files.</p>
+<p>The default mode &quot;auto&quot; will try for <code>hardened</code> signing if the debug level is <code>release</code> and either the default identity or the specified identity is valid. If hardened isn't possible, then <code>debug</code> signing is chosen if it works. If nothing works, the codesign build step is disabled.</p>
 <h2 id="cross-compiling">Cross-compiling</h2>
 <p>Cross-compiling means using one platform (the <em>build</em> platform) to generate output that can ran on another platform (the <em>target</em> platform).</p>
 <p>The typical reason for cross-compiling is that the build is performed on a more powerful desktop computer, but the resulting binaries will be able to run on a different, typically low-performing system. Most of the complications that arise when building for embedded is due to this separation of <em>build</em> and <em>target</em> systems.</p>
 <p>This requires a more complex setup and build procedure. This section assumes you are familiar with cross-compiling in general, and will only deal with the particularities of cross-compiling the JDK. If you are new to cross-compiling, please see the <a href="https://en.wikipedia.org/wiki/Cross_compiler#External_links">external links at Wikipedia</a> for a good start on reading materials.</p>
 <p>Cross-compiling the JDK requires you to be able to build both for the build platform and for the target platform. The reason for the former is that we need to build and execute tools during the build process, both native tools and Java tools.</p>
 <p>If all you want to do is to compile a 32-bit version, for the same OS, on a 64-bit machine, consider using <code>--with-target-bits=32</code> instead of doing a full-blown cross-compilation. (While this surely is possible, it's a lot more work and will take much longer to build.)</p>
+<h3 id="cross-compiling-the-easy-way-with-openjdk-devkits">Cross compiling the easy way with OpenJDK devkits</h3>
+<p>The OpenJDK build system provides out-of-the box support for creating and using so called devkits. A <code>devkit</code> is basically a collection of a cross-compiling toolchain and a sysroot environment which can easily be used together with the <code>--with-devkit</code> configure option to cross compile the OpenJDK. On Linux/x86_64, the following command:</p>
+<pre><code>bash configure --with-devkit=&lt;devkit-path&gt; --openjdk-target=ppc64-linux-gnu &amp;&amp; make</code></pre>
+<p>will configure and build OpenJDK for Linux/ppc64 assuming that <code>&lt;devkit-path&gt;</code> points to a Linux/x86_64 to Linux/ppc64 devkit.</p>
+<p>Devkits can be created from the <code>make/devkit</code> directory by executing:</p>
+<pre><code>make [ TARGETS=&quot;&lt;TARGET_TRIPLET&gt;+&quot; ] [ BASE_OS=&lt;OS&gt; ] [ BASE_OS_VERSION=&lt;VER&gt; ]</code></pre>
+<p>where <code>TARGETS</code> contains one or more <code>TARGET_TRIPLET</code>s of the form described in <a href="https://sourceware.org/autobook/autobook/autobook_17.html">section 3.4 of the GNU Autobook</a>. If no targets are given, a native toolchain for the current platform will be created. Currently, at least the following targets are known to work:</p>

+<p><code>BASE_OS</code> must be one of &quot;OEL6&quot; for Oracle Enterprise Linux 6 or &quot;Fedora&quot; (if not specified &quot;OEL6&quot; will be the default). If the base OS is &quot;Fedora&quot; the corresponding Fedora release can be specified with the help of the <code>BASE_OS_VERSION</code> option (with &quot;27&quot; as default version). If the build is successful, the new devkits can be found in the <code>build/devkit/result</code> subdirectory:</p>
+<pre><code>cd make/devkit
+make TARGETS=&quot;ppc64le-linux-gnu aarch64-linux-gnu&quot; BASE_OS=Fedora BASE_OS_VERSION=21
+ls -1 ../../build/devkit/result/
+x86_64-linux-gnu-to-aarch64-linux-gnu
+x86_64-linux-gnu-to-ppc64le-linux-gnu</code></pre>
+<p>Notice that devkits are not only useful for targeting different build platforms. Because they contain the full build dependencies for a system (i.e. compiler and root file system), they can easily be used to build well-known, reliable and reproducible build environments. You can for example create and use a devkit with GCC 7.3 and a Fedora 12 sysroot environment (with glibc 2.11) on Ubuntu 14.04 (which doesn't have GCC 7.3 by default) to produce OpenJDK binaries which will run on all Linux systems with runtime libraries newer than the ones from Fedora 12 (e.g. Ubuntu 16.04, SLES 11 or RHEL 6).</p>

A number of pre-defined ABI profiles are available using <code>--with-abi-profile</code>: arm-vfp-sflt, arm-vfp-hflt, arm-sflt, armv5-vfp-sflt, armv6-vfp-hflt. Note that soft-float ABIs are no longer properly supported by the JDK.</p>
 <p>The JDK contains two different ports for the aarch64 platform, one is the original aarch64 port from the <a href="http://openjdk.java.net/projects/aarch64-port">AArch64 Port Project</a> and one is a 64-bit version of the Oracle contributed ARM port. When targeting aarch64, by the default the original aarch64 port is used. To select the Oracle ARM 64 port, use <code>--with-cpu-port=arm64</code>. Also set the corresponding value (<code>aarch64</code> or <code>arm64</code>) to --with-abi-profile, to ensure a consistent build.</p>

+## 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.
 
 ## Cross-compiling
 
@@ -875,6 +940,64 @@ If all you want to do is to compile a 32-bit version, for the same OS, on a
 full-blown cross-compilation. (While this surely is possible, it's a lot more
 work and will take much longer to build.)
 
+### Cross compiling the easy way with OpenJDK devkits
+
+The OpenJDK build system provides out-of-the box support for creating and using
+so called devkits. A `devkit` is basically a collection of a cross-compiling
+toolchain and a sysroot environment which can easily be used together with the
+`--with-devkit` configure option to cross compile the OpenJDK. On Linux/x86_64,
+the following command:
+```
+bash configure --with-devkit=<devkit-path> --openjdk-target=ppc64-linux-gnu && make
+```
+
+will configure and build OpenJDK for Linux/ppc64 assuming that `<devkit-path>`
+points to a Linux/x86_64 to Linux/ppc64 devkit.
+
+Devkits can be created from the `make/devkit` directory by executing:
+```
+make [ TARGETS="<TARGET_TRIPLET>+" ] [ BASE_OS=<OS> ] [ BASE_OS_VERSION=<VER> ]
+```
+
+where `TARGETS` contains one or more `TARGET_TRIPLET`s of the form
+described in [section 3.4 of the GNU Autobook](
+https://sourceware.org/autobook/autobook/autobook_17.html). If no
+targets are given, a native toolchain for the current platform will be
+created. Currently, at least the following targets are known to work:
+
+| Supported devkit targets |
+| ------------------------ |
+| x86_64-linux-gnu         |
+| aarch64-linux-gnu        |
+| arm-linux-gnueabihf      |
+| ppc64-linux-gnu          |
+| ppc64le-linux-gnu        |
+| s390x-linux-gnu          |
+
+`BASE_OS` must be one of "OEL6" for Oracle Enterprise Linux 6 or
+"Fedora" (if not specified "OEL6" will be the default). If the base OS
+is "Fedora" the corresponding Fedora release can be specified with the
+help of the `BASE_OS_VERSION` option (with "27" as default version).
+If the build is successful, the new devkits can be found in the
+`build/devkit/result` subdirectory:
+```
+cd make/devkit
+make TARGETS="ppc64le-linux-gnu aarch64-linux-gnu" BASE_OS=Fedora BASE_OS_VERSION=21
+ls -1 ../../build/devkit/result/
+x86_64-linux-gnu-to-aarch64-linux-gnu
+x86_64-linux-gnu-to-ppc64le-linux-gnu
+```
+
+Notice that devkits are not only useful for targeting different build
+platforms. Because they contain the full build dependencies for a
+system (i.e. compiler and root file system), they can easily be used
+to build well-known, reliable and reproducible build environments. You
+can for example create and use a devkit with GCC 7.3 and a Fedora 12
+sysroot environment (with glibc 2.11) on Ubuntu 14.04 (which doesn't
+have GCC 7.3 by default) to produce OpenJDK binaries which will run on
+all Linux systems with runtime libraries newer than the ones from
+Fedora 12 (e.g. Ubuntu 16.04, SLES 11 or RHEL 6).

   * If the X11 libraries are not properly detected by `configure`, you can
     point them out by `--with-x`.
 
+### Cross compiling with Debian sysroots
+
+Fortunately, you can create sysroots for foreign architectures with tools
+provided by your OS. On Debian/Ubuntu systems, one could use `qemu-deboostrap` to
+create the *target* system chroot, which would have the native libraries and headers
+specific to that *target* system. After that, we can use the cross-compiler on the *build*
+system, pointing into chroot to get the build dependencies right. This allows building
+for foreign architectures with native compilation speed.
+
+For example, cross-compiling to AArch64 from x86_64 could be done like this:
+
+  * Install cross-compiler on the *build* system:
+    ```
+    apt install g++-aarch64-linux-gnu gcc-aarch64-linux-gnu
+    ```
+
+  * Create chroot on the *build* system, configuring it for *target* system:
+    ```
+    sudo qemu-debootstrap \
+      --arch=arm64 \
+      --verbose \
+      --include=fakeroot,symlinks,build-essential,libx11-dev,libxext-dev,libxrender-dev,libxrandr-dev,libxtst-dev,libxt-dev,libcups2-dev,libfontconfig1-dev,libasound2-dev,libfreetype6-dev,libpng-dev,libffi-dev \
+      --resolve-deps \
+      buster \
+      ~/sysroot-arm64 \
+      http://httpredir.debian.org/debian/
+    ```
+
+  * Make sure the symlinks inside the newly created chroot point to proper locations:
+    ```
+    sudo chroot ~/sysroot-arm64 symlinks -cr .
+    ```
+
+  * Configure and build with newly created chroot as sysroot/toolchain-path:
+    ```
+    sh ./configure \
+      --openjdk-target=aarch64-linux-gnu \
+      --with-sysroot=~/sysroot-arm64
+    make images
+    ls build/linux-aarch64-normal-server-release/
+    ```
+
+The build does not create new files in that chroot, so it can be reused for multiple builds
+without additional cleanup.
+
+The build system should automatically detect the toolchain paths and dependencies, but sometimes
+it might require a little nudge with:
+
+  * Native compilers: override `CC` or `CXX` for `./configure`
+
+  * Freetype lib location: override `--with-freetype-lib`, for example `${sysroot}/usr/lib/${target}/`
+
+  * Freetype includes location: override `--with-freetype-include` for example `${sysroot}/usr/include/freetype2/`
+
+  * X11 libraries location: override `--x-libraries`, for example `${sysroot}/usr/lib/${target}/`

+% IDE support in the JDK
+
+## Introduction
+
+When you are familiar with building and testing the JDK, you may want to
+configure an IDE to work with the source code. The instructions differ a bit
+depending on whether you are interested in working with the native (C/C++) or
+the Java code.
+
+### IDE support for native code
+
+There are a few ways to generate IDE configuration for the native sources,
+depending on which IDE to use.
+
+#### Visual Studio Code
+
+The make system can generate a [Visual Studio Code](https://code.visualstudio.com)
+workspace that has C/C++ source indexing configured correctly, as well as
+launcher targets for tests and the Java launcher. After configuring, a workspace
+for the configuration can be generated using:
+
+```shell
+make vscode-project
+```
+
+This creates a file called `jdk.code-workspace` in the build output folder. The
+full location will be printed after the workspace has been generated. To use it,
+choose `File -> Open Workspace...` in Visual Studio Code.
+
+##### Alternative indexers
+
+The main `vscode-project` target configures the default C++ support in Visual
+Studio Code. There are also other source indexers that can be installed, that
+may provide additional features. It's currently possible to generate
+configuration for two such indexers, [clangd](https://clang.llvm.org/extra/clangd/)
+and [rtags](https://github.com/Andersbakken/rtags). These can be configured by
+appending the name of the indexer to the make target, such as:
+
+```shell
+make vscode-project-clangd
+```
+
+Additional instructions for configuring the given indexer will be displayed
+after the workspace has been generated.
+
+#### Visual Studio
+
+This section is a work in progress.
+
+```shell
+make ide-project
+```
+
+#### Compilation Database
+
+The make system can generate generic native code indexing support in the form of
+a [Compilation Database](https://clang.llvm.org/docs/JSONCompilationDatabase.html)
+that can be used by many different IDEs and source code indexers.
+
+```shell
+make compile-commands
+```
+
+It's also possible to generate the Compilation Database for the HotSpot source
+code only, which is a bit faster as it includes less information.
+
+```shell
+make compile-commands-hotspot
+```
+
+### IDE support for Java code
+
+This section is a work in progress.

 <h2 id="using-the-run-test-framework">Using 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 “run-test” uses the jdk-image as the tested product. There is also an alternate target “exploded-run-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.</p>

GitHub Actions workflows, if enabled, run <code>tier1</code> tests.</p></li>

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.

+Set to `true` or `false`.
+If `true`, JTReg will use `-match:` option, otherwise `-exclude:` will be used.

+## 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:
+
+    $ make run-test TEST="jtreg:test/hotspot/jtreg/containers/docker"
+
+To run these tests correctly, additional parameters for the correct docker image are
+required on Ubuntu 18.04 by using `JAVA_OPTIONS`.
+
+    $ make run-test TEST="jtreg:test/hotspot/jtreg/containers/docker" JTREG="JAVA_OPTIONS=-Djdk.test.docker.image.name=ubuntu -Djdk.test.docker.image.version=latest"
+
+### 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 `jdk.test.lib.artifacts.<NAME>` is required on
+Ubuntu 18.04 to specify the alternative NSS lib directory. The `<NAME>`
+component should be replaced with the name element of the appropriate
+`@Artifact` class. (See `test/jdk/sun/security/pkcs11/PKCS11Test.java`)
+For example:
+
+    $ make test TEST="jtreg:sun/security/pkcs11/Secmod/AddTrustedCert.java" JTREG="JAVA_OPTIONS=-Djdk.test.lib.artifacts.nsslib-linux_aarch64=/path/to/NSS-libs"
+
+For more notes about the PKCS11 tests, please refer to test/jdk/sun/security/pkcs11/README.
+
+### 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.
+
+#### 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.
+
+#### Linux
+Open the Activities overview and start typing Settings; Choose Settings, click Devices,
+then click Keyboard; set or override desired shortcut.
+
+#### Windows
+Type `gpedit` in the Search and then click Edit group policy; navigate to
+User Configuration -> Administrative Templates -> Windows Components -> File Explorer;
+in the right-side pane look for "Turn off Windows key hotkeys" and double click on it;
+enable or disable hotkeys.
+
+Note: restart is required to make the settings take effect.
