-% Migration of JDK Classes to Value Classes
-
-## Introduction
-
-The Value Objects feature introduces value objects and migrates suitable classes
-to value classes. This means that when preview features are enabled, different
-class files are used for the migrated classes in the Java class library.
-
-To accomplish this, a built JDK uses *preview-specific* files in `META-INF/preview`,
-which overrides the regular files of the same name. For example,
-`META-INF/preview/java/lang/Integer.class` overrides `java/lang/Integer.class`.
-
-The JDK generates preview-specific source files (they may use preview language
-features), compiles class files from them, and distributes these class files in
-`META-INF/preview`.
-
-## The Build Process
-
-### The Custom Handling for the Value Objects JEP
-
-The Value Objects JEP requires a few select classes in the `java.base` module
-to become value classes when preview features are enabled.
-
-The build of `java.base` module first creates the source code of those value
-classes, done in
-[`GensrcValueClasses.gmk`](../make/modules/java.base/gensrc/GensrcValueClasses.gmk).
-
-1. A hardcoded list of regular source files are selected for preview-specific
-   generation.
-
-2. Extract the content of each regular source file, search for any occurrences
-   of `/*value*/ class` or `/*value*/ record`, and replace with `value class`
-   or `value record`.
-
-3. The replaced contents are written to the preview-specific generated files,
-   located in `support/gensrc-valueclasses/java.base/`.  The regular source
-   files remain unchanged in their original locations.
-
-4. The general preview source to binary build pipeline recognizes the
-   `support/gensrc-valueclasses/java.base/` directory as where the `java.base`
-   module places its preview-specific source files.
-
-### The General Preview Source to Binary Pipeline
-
-Once the preview-specific source files are ready, they are picked up by the
-build system into a fully automated pipeline handling all modules and all
-outcome images.
-
-1. The `GENERATED_PREVIEW_SUBDIRS` variable in [`make/common/Modules.gmk`](../make/common/Modules.gmk)
-   indicates where the source files are found.
-
-2. For each module that has preview-specific source files, a goal is created
-   to compile these source files into class files.
-
-3. The class files from each of these tasks reside in `support/preview/<module>`
-   for each module.
-
-4. These preview-specific class files and other resources are copied to the
-   `META-INF/preview` directory of the regular output directory.
-
-5. At run-time, jimage will pick up the preview-specific overrides from
-   `META-INF/preview` only when preview features are enabled.
-
-6. The interim javac used by the build system cannot pick up the
-   preview-specific overrides; they must be supplied explicitly with the
-   following javac flag for every single module where overrides are significant:
-
-   ```
-   --patch-module <module>=$(SUPPORT_OUTPUTDIR)/preview/<module>
-   ```
-
-   See [`BuildMicroBenchmarks.gmk`](../make/test/BuildMicrobenchmark.gmk) for an example.
-
-### Non-Goals
-
-The Value Objects JEP only plans to introduce value classes that are:
-
-1. In the `java.base` module.
-
-   There's no plan to migrate other classes in other modules.
-
-2. Migrated from existing classes.
-
-   These classes are available as identity classes when preview features are
-   disabled. There's no plan to introduce completely new value classes.
-
-Support for other value classes would require significant changes to the build
-system.
-
-## Testing
-
-In addition to tests that require preview features to be enabled, tests that do
-not depend on preview features wish to run with preview features enabled to
-ensure compatibility:
-
-1. Some tests wish to run against the Java SE class library with value classes.
-
-   The jtreg tests may be run with `JTREG=VM_OPTIONS=--enable-preview`.
-
-2. Some tests wish to run against their own classes migrated to value classes.
-
-   The jtreg [VALUE_CLASS_PLUGIN](testing.html#VALUE_CLASS_PLUGIN) allows tests
-   to migrate their own classes to value classes when running with the plugin.
-
-## Wrapper Class Caches
-
-Currently, wrapper class caches are retained even when preview features are
-enabled to address performance losses. They have no semantic impact to value
-objects.
-
-In interpreter or C1 execution in Hotspot, allocations of a value object to the
-heap as a full object with header happen when a value object is:
-
-1. Loaded from a flat storage (field or array)
-2. Created by a constructor
-3. If C2 uses scalarized calling convention, at C2 to C1/interpreter calls and returns
-
-Ideally, C2 can eliminate such allocations, but this does not work if the
-resulting object is stored into references. Unfortunately, many uses of boxing
-conversions store the resulting wrapper objects as references.
-
-For the uses that store wrapper objects to references, if the boxing
-conversion is:
-
-1. Returning a value object from a flat cache array
-2. Calling the value class constructor
-
-Then we would have heap allocation on every single use.
-
-To avoid the allocations, we fall back to returning a value object from a
-reference cache array, from which the loaded reference is directly storable
-into a destination that wants a reference without any allocation.
-
-Since Hotspot may create flat arrays if an array of value objects is requested
-by regular Java array creation mechanisms, we use `ValueClass.newReferenceArray`
-to ensure we always create a reference cache array.
-
-The cache array for value objects may be removed without notice if the
-performance losses from allocations are no longer significant.
