Seen as an intermittent failure in DataRehashedEventTest:

The initial cluster has 3 nodes: A, B, C. C is killed, but somehow remains in the ClusterCacheStatus on the coordinator.
Then C re-appears in the JGroups view (possibly a JGroups issue). The problem in Infinispan is that the coordinator now sees C as a joiner, and it rebalances the cache to include C in the consistent hash again.
