As an intermediate fix to the test, switching to explicit usage of an ExecutorService seems to do the trick to make this test reliably pass.
With that said, this test (CHM::ToArray.java) seems to trigger an issue in ForkJoinPool, so that would need to be fixed separately. Tagging @DougLea as an FYI. :) ------------- Commit messages: - Switching CHM.ToArray test to use a dedicated thread pool Changes: https://git.openjdk.org/jdk/pull/18023/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=18023&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8269428 Stats: 49 lines in 1 file changed: 3 ins; 0 del; 46 mod Patch: https://git.openjdk.org/jdk/pull/18023.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/18023/head:pull/18023 PR: https://git.openjdk.org/jdk/pull/18023
