This PR proposes adding `@Stable` to certain wrapper classes' cache arrays (e.g. `Integer` and `Long`).
Comments are welcome as to how to improve the VM's handling now that the backing cache array is `@Stable`. Are there simplifications to be made or are there other optimizations we might add? ------------- Commit messages: - Fix trailing white spaces - Reinsert row - Annotate CharacterCache @Stable - Mark caching arrays @Stable Changes: https://git.openjdk.org/jdk/pull/14418/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=14418&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8295555 Stats: 16 lines in 5 files changed: 11 ins; 0 del; 5 mod Patch: https://git.openjdk.org/jdk/pull/14418.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/14418/head:pull/14418 PR: https://git.openjdk.org/jdk/pull/14418
