    Description

      Some tests log NullPointerException-caused error messages when they pass, which makes it hard to tell if it's a real problem or not.

      CacheManagerTest: cluster executor tests throw NullPointerException explicitly.

      11:20:04,030 WARN  (remote-thread-CacheManagerTest-NodeN-p1091-t1:) [GlobalInboundInvocationHandler] ISPN000071: Caught exception when handling command org.infinispan.manager.impl.ReplicableCommandRunnable@6c20c6c7

      Various tests, during cluster shutdown: an incoming CacheTopologyControlCommand can re-create the ClusterTopologyManager component, and call handleRebalanceCompleted() without start().

      InitialClusterSizeTest: stops the cache manager after if failed to start, and DefaultCacheManager.stop() throws an exception because the internal cache registry was not registered.
