Subject [jira] Commented: (POOL-146) Thread deadlock issue in GenericKeyedObjectPool borrowObject()
Date Sun, 05 Jul 2009 17:08:14 GMT


Mark Thomas commented on POOL-146:

OK, now I understand.

That is a bug although making the Latch object global is not the way to address this. I have
added a test case and am working on a patch.
