"Trying to set a topology with invalid members" in JBoss EAP 6

Issue

• New members cannot join the cluster, with a state transfer timeout exception. Before this condition occurs, the coordinator logs the following:

  ISPN000196: Failed to recover cluster state after the current node became the coordinator: java.lang.IllegalStateException: Trying to set a topology with invalid members for cache remote-connector-client-mappings: members = [member2/ejb, member3/ejb], topology = CacheTopology{id=123, currentCH=ReplicatedConsistentHash{members=[member1/ejb, member2/ejb, member3/ejb]}, pendingCH=null}
