Description Radim Vansa 2014-10-15 07:05:20 UTC 
After split brain: when calling cache.get() for an entry that has all owners in the missing partition, JGroupsTransport removes the target nodes that are no longer members and then returns empty response map
BaseDistributionInterceptor.invokeClusterGetCommandRemotely takes empty map as null response, although the entry is just not available.
