Folks, You may find interesting investigations in HARMONY-1519 [1] of bugs in patched APR condition variables on Win32, which affect wait() behavior.
[1]http://issues.apache.org/jira/browse/HARMONY-1519?page=all 2006/9/25, Weldon Washburn <[EMAIL PROTECTED]>:
The hang on gc.LOS on windows has been present for at least one week. I broke into the hung DRLVM with microsoft debugger. Its running jitted code that loops. The loop seems to involve synchronization primitives (see email chain "[drlvm] gc.LOS hangs on win32") I still suspect a bug that is somehow associated with Object.wait(). Its interesting to note what recently changed that might have an impact: - new thread manager - launcher was integrated The launcher starts out in the context of classlib's portlib . The classlib portlib context is later on partially replaced with PORTLIB, a C struct where all the members are nulled out. Apparently signals run in the context of classlib's portlib and the new thread manager runs in its own (appropriate) context. In any case, both classlib portlib and the new threading manager have implementations of monitor_wait(). There may some conflict on when and where each version of monitor wait is called.
