Subject [jira] Commented: (HARMONY-1789) [DRLVM] Race condition between Thread.interrupt and Object.wait, Thread.sleep or join
Date Fri, 17 Nov 2006 14:33:42 GMT
    [ http://issues.apache.org/jira/browse/HARMONY-1789?page=comments#action_12450751 ] 
            
Alexey Varlamov commented on HARMONY-1789:
------------------------------------------

Well, it's all the same for multicore Win2003 server: 
- HARMONY1789 hangs without HARMONY-2217; 
- the test itself shows bad statistics for all RI, DRLVM and DRLVM+all patches;
- ThreadTest still hangs.

So, at least no regressions everywhere and slight improvement for single CPU systems on HARMONY1789
test.

> According to the specification wait/join or sleep methods should check if thread was
interrupted before entering wait. DRLVM hythread implmentation do checks interrupted status(see
hythread condition implmentation), however thread may be interrupted just after the status
was checked and before entering condition wait. Thus it's required to ensure that waiting
state will be reached having interrupted status unchanged.
