Subject [jira] Commented: (HARMONY-1789) [DRLVM] Race condition between Thread.interrupt and Object.wait, Thread.sleep or join

Elena Semukhina commented on HARMONY-1789:
------------------------------------------

Nikolay,
I tried the patch. It solves the classlib ThreadTest hanging but C unit test test_java_park
hangs now:

     [echo] ## Executing C unit test: test_java_park
                  [hangs...]

> 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.
