Subject [jira] Commented: (HARMONY-1789) [DRLVM] Race condition between Thread.interrupt and Object.wait, Thread.sleep or join
Date Thu, 26 Oct 2006 07:45:20 GMT
    [ http://issues.apache.org/jira/browse/HARMONY-1789?page=comments#action_12444822 ] 
            
Elena Semukhina commented on HARMONY-1789:
------------------------------------------

I still observe ThreadTest.testInterrupt_Sleeping() intermittent failures when running drlvm
kernel tests even after  H-1592 and H-1823 commits. But the attached test passes for me when
this.wait () replaced with Thread.sleep() in the ThreadWaiting.run() method.

> 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.
