NPE during replication #1590

Closed esebasti closed 7 years ago

esebasti commented 7 years ago

Passive entity throws & logs this NPE for every message it applies.

Just to add to that, this behavior is seen only with eventual caches when a passive is brought up while mutative cache operations are in progress (mix up replication and sync).

This is die to the fact that no invalidation tracking is being done for eventual caches during creation while sync. Please see this PR for reference https://github.com/ehcache/ehcache3/pull/1588.
