Please review the application of the `@Serial` annotation ([JDK-8202385](https://bugs.openjdk.org/browse/JDK-8202385)) to types in the `java.management.*` modules. The goal is to enable stricter compile-time checking of serialization-related declarations.
The change is not small. I could split it, but I decided to do it as a single change since covering the module in one shot is easier than managing a bunch of separate PRs. Example of a similar change https://github.com/openjdk/jdk/pull/24891. Note: this annotation can be applied to these methods and fields: * private void writeObject(java.io.ObjectOutputStream stream) throws IOException * private void readObject(java.io.ObjectInputStream stream) throws IOException, ClassNotFoundException * private void readObjectNoData() throws ObjectStreamException * ANY-ACCESS-MODIFIER Object writeReplace() throws ObjectStreamException * ANY-ACCESS-MODIFIER Object readResolve() throws ObjectStreamException * private static final ObjectStreamField[] serialPersistentFields * private static final long serialVersionUID Additional changes: - Copyright years were updated - Imports were not touched much (no sorting or cleanup); the new import was added in a reasonable place - In several places `static final long serialVersionUID =` was changed to `private static final long serialVersionUID =` ------------- Commit messages: - 8374838: Apply java.io.Serial annotations in javax.management.* Changes: https://git.openjdk.org/jdk/pull/29145/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=29145&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8374838 Stats: 550 lines in 138 files changed: 382 ins; 0 del; 168 mod Patch: https://git.openjdk.org/jdk/pull/29145.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/29145/head:pull/29145 PR: https://git.openjdk.org/jdk/pull/29145
