Valid point. Adjusted test to use daemon threads for the concurrent access tests. I reran the tests on the baseline JDK and after the changes to verify the findings from https://github.com/openjdk/jdk/pull/24614#issuecomment-2884495131. Did not notice this as the jtreg harness indeed seems to terminate the JVM and not report that as a failure, tested now also manually (without jtreg).
