Gregory Shimansky commented on HARMONY-2817:
--------------------------------------------
I tried the updated patch. It still causes problems for me on windows. The test gc.LOS crashes on interpreter somewhere in GC.
On x86_64 SuSE9 stress.Sync hanged again. It hangs on JIT too after printing PASSED. Note I've used powerful 4 CPU with HT (8 logical processors) server for x86_64, maybe we have some race condition which is reproducible only when a lot of stuff works in parallel.

--------------------------------------------
The patch makes new smoke tests to hang (on Linux ia32) and crash (on Windows XP) on interpreter. Please check these tests with it. I can give the details if you need. I've reverted the changes and smoke tests on interpreter work again.

Attachment: java_shutdown_fix3.patch
Gregory,
I believe this patch will fix your crash on interpreter. It turned out that "interp_resolve_class" enables thread suspention inside even though it is called is susend disabled state. So the following code is not safe:
hythread_suspend_disable()
obj = ObjectHandle->object;
interp_resolve_class();
ObjectHandle->object = obj;
hythread_suspend_disable()
I think "interp_resolve_class" should be fixed in the future....
Note: stress.Sync still hangs on JIT. I will investigate it separately.

------------------------------------------
Gregory,
Hmm.... it is pitty we have a crash on the interpreter. I'll look through the patch once again to see where the problem is.
About stress.Sync. I didn't change the behaviour on JIT at all (almost :-)). This patch should affect interpreter only. Yes, stress.Sync hangs for me sometimes :-(....This needs additional investigation....It may turn out to be a JIT specific problem....IMHO This should not prevent us from commiting this patch as soon as interpreter is OK.
BTW.. I've observed hangs of gc.LOS. It appeared to be hanging inside system library. Seems like we still have problems with native locks.

Elena,
I looked at the dump file provided by you. The problem you met is connected with safe point callbacks implementation. A deadlock you have is described under 1 item in the https://issues.apache.org/jira/browse/HARMONY-2648.

--------------------------------------------
I've done a nightly run of this test on interpreter on 4 CPU SuSE9 linux server. For me this test passed 3320 times and still continued to run when I killed it. Maybe there should be more specific information about how to catch this bug.

Attachment: java_shutdown_fix4.patch
Huh... I finally found the reason why stress.Sync hangs. It turned out to be a problem with asynchronious exceptions which caused thread to exit without releasing monitors. Fixed in java_shutdown_fix4.patch. DRLVM tests are OK on Win2003-ia32 & SUSE9-32. stress.Sync consequently passed 160 times on JIT & Interpreter on SUSE10 16-logical processors.
