LGTM. As I noted in [this comment on JDK-8353644](https://bugs.openjdk.org/browse/JDK-8353644?focusedId=14772997&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14772997), I was able to run the test 1,000 times in a row with no failures on our Ubuntu 24.04 test system.
