Please review the following change: Bug: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7132070
Webrev: http://cr.openjdk.java.net/~sla/7132070/webrev.00/ This changes the value returned by OSThread::thread_id() and os::current_thread_id() on macosx to return the mach thread_t instead of pthread_t. There is a separate method OSThread:pthread_id() that returns the pthread_t. The reason for this change is both that JFR would like a 4 byte value for thread id, and that SA requires access to the thread_t. Thanks, /Staffan
