Please review this fix for DwarfParser cleaner. The original code registered the cleaner using a lambda that captured a reference to the parser object; as a result, the object was never GCed, and the cleaner never ran.
In this version I moved the lambda creation to a static method, so that it can't capture a reference to the parser. Additionally, the new code uses a static cleaner; the cleaner object creation and cleanup are heavy operations (every cleaner comes with its own thread), and it's preferable to use a single shared cleaner where possible. I verified manually that the native `destroyDwarfContext` method is called after this fix. No new automated test. Existing tier1-2 tests continue to pass. ------------- Commit messages: - Fix dwarf cleaner Changes: https://git.openjdk.org/jdk/pull/11965/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=11965&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8300032 Stats: 8 lines in 1 file changed: 5 ins; 1 del; 2 mod Patch: https://git.openjdk.org/jdk/pull/11965.diff Fetch: git fetch https://git.openjdk.org/jdk pull/11965/head:pull/11965 PR: https://git.openjdk.org/jdk/pull/11965
