Subject [jira] [Commented] (FELIX-5443) Frequent Changes cause UpdateThread to ConcurrentModificationException
Date Thu, 22 Dec 2016 05:52:58 GMT

Carsten Ziegeler commented on FELIX-5443:
-----------------------------------------

:) I'm not sure if locking all PID is really increasing complexity. Looking at your patch,
you do a locking on the factory (pid) which is basically the same as I suggest. The difference
being that your patch does it only for factory configurations
