Dennis Reed commented on JGRP-1383:
-----------------------------------
It is resolved for 2.6.
I left it open until I check master to see if it is an issue there also
(and have been very busy, hopefully I'll get to it in the next week or so).
ConcurrentModificationException in BasicConnectionTable.retainAll

Key: JGRP-1383
URL: https://issues.jboss.org/browse/JGRP-1383

...
BasicTCP is missing a synchoronize on "members" when it passes it to
TCP.retainAll.
If members is modified by another thread (in TP.handleDownEvent) while
BasicConnectionTable's Set.removeAll
call is iterating over it, it triggers a ConcurrentModificationException.
