In the JVM on BSD, a thread is represented by two different thread id value= s, however, only when defined(__APPLE__) does the second value, unique_thread_= id, get set. Its unique_thread_id that jstack uses to match thread ids in a core dump. I've been using the attached two local patches. patch-rjr-os_bsd.cpp sets unique_thread_id to the same value as the thread_= id. patch-rjr-BsdThread.java adds the unique_thread_id to BsdThread.toString() output. --=20 You are receiving this mail because: You are the assignee for the bug.=
