This makes the test pass. Jim is right. The compiler thread is suspended and the thread2 is blocked for compilation while debugger is waiting for breakpoint. I think testcase should not suspend compiler thread and resume java thread and expect for java thread to hit the breakpoint. Thanks, Swamy ###@###.### 2002-02-05 Finally we have decided not to allow suspend and resume of compiler threads. So we will filter out the compiler thread information and disallow suspend and resume of compiler thread. Thanks, Swamy

SUGGESTED FIX See the attached webrev. NOTE: The attached webrev is incomplete. The following diff is also required in src/share/vm/prims/jvmdi.cpp (note that these line numbers might be a little off) src/share/vm/prims/jvmdi.cpp: 2816c2816 < for (int i=0; i<nthreads; i++) { --- > for (int i=0, j=0; i<nthreads; i++) { 2818c2818 < assert(thread_obj != NULL, "thread_obj != NULL"); --- > assert(thread_obj != NULL, "thread_obj is NULL"); 2825c2825 < thread_objs[i] = thread_obj; --- > thread_objs[j++] = thread_obj; See also bug 4688375. ###@###.### 2002-06-03
