The vmTestbase/nsk/share/LocalProcess.java is a wrapper for debuggee process. It extends FinalizableObject to kill the debuggee process.
The debuggee process is used by nsk.jdb tests only, see runTest(...) in vmTestbase/nsk/share/jdb/JdbTest.java: https://github.com/openjdk/jdk/blob/master/test/hotspot/jtreg/vmTestbase/nsk/share/jdb/JdbTest.java#L189 I verified that process is always already terminated when is cleaned during VM shutdown hook, So the fix is just to remove the finalization. I also moved LocalProcess into nsk.share.jdb to reduce the visibility of class and hardened checks in runTest. ------------- Commit messages: - 8333013: Update vmTestbase/nsk/share/LocalProcess.java to don't use finalization Changes: https://git.openjdk.org/jdk/pull/19418/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=19418&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8333013 Stats: 343 lines in 3 files changed: 156 ins; 179 del; 8 mod Patch: https://git.openjdk.org/jdk/pull/19418.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/19418/head:pull/19418 PR: https://git.openjdk.org/jdk/pull/19418
