      This problem is exposed by runtime/InternalApi/ThreadCpuTimesDeadlock.java test with ShenandoahGC.

      Thread list contains newly allocated/born thread, has yet made runnable, e.g. thread_id = 0.

      For this particular test, when it iterates through threads with ThreadTimesClosure, it may crash in pthread_getcpuclockid() call if the thread has thread_id = 0.
