unknowntpo opened a new pull request, #22827: URL: https://github.com/apache/kafka/pull/22827
## Summary - skip detected threads that terminate before the thread-leak report is built - add a regression test covering the terminated-thread race ## Motivation `ClusterTestExtensions#afterEach` formats detected threads with `Thread#getThreadGroup().getName()`. A thread can terminate after `DetectThreadLeak#newThreads()` captures it but before the message is formatted. Since `Thread#getThreadGroup()` returns `null` for a terminated thread, the reporting path throws an NPE even though the thread is no longer a leak.
