[jboss-dev-forums] [Design of Messaging on JBoss (Messaging/JBoss)] - Re: Symmetric Cluster Example fails on a multi-core machine

In one of these runs (only one)  I saw a ConcurrentModificationException on DiscoveryGroupImpl::listeners during a call to DiscoveryGroupImpl::callListeners.

callListeners is not synchronized what would make sense.

I thought it would be somehow related to this. So I made it synchronized but nothing changed on the behaviour (still have failures).
