Description
When the joiner becomes the coordinator, it tries to recover the current cache topologies, but it receives just one expected member and no current topology. This causes a NPE in ClusterCacheStatus:
22:51:49,547 ERROR (transport-thread-NodeB-p21124-t1:) [ClusterCacheStatus] ISPN000228: Failed to recover cache dist state after the current node became the coordinator java.lang.NullPointerException at org.infinispan.partionhandling.impl.PreferAvailabilityStrategy.onPartitionMerge(PreferAvailabilityStrategy.java:104) at org.infinispan.topology.ClusterCacheStatus.doMergePartitions(ClusterCacheStatus.java:452) at org.infinispan.topology.ClusterTopologyManagerImpl.recoverClusterStatus(ClusterTopologyManagerImpl.java:260) at org.infinispan.topology.ClusterTopologyManagerImpl.handleClusterView(ClusterTopologyManagerImpl.java:180) at org.infinispan.topology.ClusterTopologyManagerImpl$ClusterViewListener$1.run(ClusterTopologyManagerImpl.java:427)
The LocalTopologyManagerImpl waits a bit after receiving the SuspectException and tries again, but this time it receives a null initial topology, causing another NPE:
22:51:51,319 DEBUG (testng-GlobalKeySetTaskTest:) [LocalTopologyManagerImpl] Error sending join request for cache dist to coordinator java.lang.NullPointerException at org.infinispan.topology.LocalTopologyManagerImpl.resetLocalTopologyBeforeRebalance(LocalTopologyManagerImpl.java:222) at org.infinispan.topology.LocalTopologyManagerImpl.handleTopologyUpdate(LocalTopologyManagerImpl.java:191) at org.infinispan.topology.LocalTopologyManagerImpl.join(LocalTopologyManagerImpl.java:105) at org.infinispan.statetransfer.StateTransferManagerImpl.start(StateTransferManagerImpl.java:108)
This keeps going on until the state transfer timeout expires.
