Please review this cleanup PR which removes per-thread compiler stats from `sun.management`
This removes: * The deprecated interface method `HotspotCompilationMBean.getCompilerThreadStats()` along with the implementation method in `HotspotCompilation` * The class returned by these methods, `CompilerThreadStat` * The nested class `HotspotCompilation.CompilerThreadInfo` which now falls out of use * The field `HotspotCompilation.threads`, along with its initialization in `initCompilerCounters` Testing and verification: As this is purely a removal and cleanup PR of unused code, no updates are made on the testing side. I have verified that the string `getCompilerThreadStats` is not found in OpenJDK after this PR. ------------- Commit messages: - Remove HotspotCompilationMBean.getCompilerThreadStats() with associated implementation code Changes: https://git.openjdk.org/jdk/pull/18344/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=18344&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8328341 Stats: 149 lines in 3 files changed: 0 ins; 147 del; 2 mod Patch: https://git.openjdk.org/jdk/pull/18344.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/18344/head:pull/18344 PR: https://git.openjdk.org/jdk/pull/18344
