+% Explanation of start of release changes
+
+## Overview
+
+The start of release changes, the changes that turn JDK _N_ into JDK
+(_N_+1), are primarily small updates to various files along with new files to
+store symbol information to allow `javac --release N ...` to run on
+JDK (_N_+1).
+
+The updates include changes to files holding meta-data about the
+release, files under the `src` directory for API and tooling updates,
+and incidental updates under the `test` directory.
+
+## Details and file updates
+
+As a matter of policy, there are a number of semantically distinct
+concepts which get incremented separately at the start of a new
+release:
+
+* Feature value of `Runtime.version()`
+* Highest source version modeled by `javax.lang.model.SourceVersion`
+* Highest class file format major version recognized by the platform
+* Highest `-source`/`-target`/`--release` argument recognized by
+  `javac` and related tools
+
+The expected file updates are listed below. Additional files may need
+to be updated for a particular release.
+
+### Meta-data files
+
+* `jcheck/conf`: update meta-data used by `jcheck` and the Skara tooling
+* `make/conf/version-numbers.conf`: update to meta-data used in the build
+
+### `src` files
+
+* `src/hotspot/share/classfile/classFileParser.cpp`: add a `#define`
+  for the new version
+* `src/java.base/share/classes/java/lang/classfile/ClassFile.java`:
+  add a constant for the new class file format version
+* `src/java.base/share/classes/java/lang/reflect/ClassFileFormatVersion.java`:
+   add an `enum` constant for the new class file format version
+* `src/java.compiler/share/classes/javax/lang/model/SourceVersion.java`:
+  add an `enum` constant for the new source version
+* `src/java.compiler/share/classes/javax/lang/model/util/*` visitors: Update
+  `@SupportedSourceVersion` annotations to latest value. Note this update
+  is done in lieu of introducing another set of visitors for each Java
+  SE release.
+* `src/jdk.compiler/share/classes/com/sun/tools/javac/code/Source.java`:
+   add an `enum` constant for the new source version internal to `javac`
+* `src/jdk.compiler/share/classes/com/sun/tools/javac/jvm/ClassFile.java`:
+   add an `enum` constant for the new class file format version internal to `javac`
+* `src/jdk.compiler/share/classes/com/sun/tools/javac/jvm/Target.java`:
+   add an `enum` constant for the new target version internal to `javac`
+* `src/jdk.compiler/share/classes/com/sun/tools/javac/processing/PrintingProcessor.java`
+   update printing processor to support the new source version
+* The symbol information for `--release` is stored as new text files in the
+  `src/jdk.compiler/share/data/symbols` directory, one file per
+  module. The README file in that directory contains directions on how
+  to create the files.
+
+### `test` files
+
+* `test/langtools/tools/javac/api/TestGetSourceVersions.java`: add new `SourceVersion` constant to test matrix.
+* `test/langtools/tools/javac/classfiles/ClassVersionChecker.java`: add new enum constant for the new class file version
+* `test/langtools/tools/javac/lib/JavacTestingAbstractProcessor.java`
+   update annotation processor extended by `javac` tests to cover the new source version
+* `test/langtools/tools/javac/preview/classReaderTest/Client.nopreview.out` and `test/langtools/tools/javac/preview/classReaderTest/Client.preview.out`: update expected messages for preview errors and warnings

+<p>One way to improve test coverage of ahead-of-time (AOT) optimizations

+    TEST=open/test/hotspot/jtreg/runtime/invokedynamic</code></pre>
+<p>In this testing mode, we first perform an AOT training run (see
+https://openjdk.org/jeps/483) of a special test program (<a
+href="../test/setup_aot/TestSetupAOT.java">test/setup_aot/TestSetupAOT.java</a>)
+that accesses about 5,0000 classes in the JDK core libraries.
+Optimization artifacts for these classes (such as pre-linked lambda
+expressions, execution profiles, and pre-generated native code) are
+stored into an AOT cache file, which will be used by all the JVMs
+launched by the selected jtreg test cases.</p>
+<p>When the jtreg tests call into the core libraries classes that are in
+the AOT cache, we will be able to test the AOT optimizations that were
+used on those classes.</p>
+<p>Please note that not all existing jtreg test cases can be executed
+with the AOT_JDK mode. See <a
+href="../test/hotspot/jtreg/ProblemList-AotJdk.txt">test/hotspot/jtreg/ProblemList-AotJdk.txt</a>
+and <a

+the tests under <a
+href="../test/hotspot/jtreg/runtime/cds/">test/hotspot/jtreg/runtime/cds</a>,
+cannot be executed with the AOT_JDK mode.</p>
+<p>Valid values for <code>AOT_JDK</code> are <code>onestep</code> and

+### Testing Ahead-of-time Optimizations
+
+One way to improve test coverage of ahead-of-time (AOT) optimizations in
+the JDK is to run existing jtreg test cases in a special "AOT_JDK" mode.
+Example:
+
+```
+$ make test JTREG="AOT_JDK=onestep" \
+    TEST=open/test/hotspot/jtreg/runtime/invokedynamic
+```
+
+In this testing mode, we first perform an AOT training run
+(see https://openjdk.org/jeps/483) of a special test program
+([test/setup_aot/TestSetupAOT.java](../test/setup_aot/TestSetupAOT.java))
+that accesses about 5,0000 classes in the JDK core libraries.
+Optimization artifacts for these classes (such as pre-linked
+lambda expressions, execution profiles, and pre-generated native code)
+are stored into an AOT cache file, which will be used by all the JVMs
+launched by the selected jtreg test cases.
+
+When the jtreg tests call into the core libraries classes that are in
+the AOT cache, we will be able to test the AOT optimizations that were
+used on those classes.
+
+Please note that not all existing jtreg test cases can be executed with
+the AOT_JDK mode. See
+[test/hotspot/jtreg/ProblemList-AotJdk.txt](../test/hotspot/jtreg/ProblemList-AotJdk.txt)
+and [test/jdk/ProblemList-AotJdk.txt](../test/jdk/ProblemList-AotJdk.txt).
+
+Also, test cases that were written specifically to test AOT, such as the tests
+under [test/hotspot/jtreg/runtime/cds](../test/hotspot/jtreg/runtime/cds/),
+cannot be executed with the AOT_JDK mode.
+
+Valid values for `AOT_JDK` are `onestep` and `twostep`. These control how
+the AOT cache is generated. See https://openjdk.org/jeps/514 for details.
+All other values are ignored.
+
 ### Testing with alternative security providers
 
 Some security tests use a hardcoded provider for `KeyFactory`, `Cipher`,
