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

Alexey Varlamov commented on HARMONY-1789:
------------------------------------------

Salikh, 
Thank you so much for thorough evaluation. And, splitting patch to related parts would really
help, I was confused to see evidently unrelated changes in a bulk.

PS. I felt a bit uneasy being obliged to express negative response, but we just cannot afford
uncotrolled fixes in TM any longer. 
Now I'm happy to see we are on the right track.

> 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.
