Scenario (typical for rollups):

Start source node, put entries.
Start target node which is pointing to source (source is his RemoteCacheStore now) and try to get entries.

For 5.2 to 5.2 working perfectly.
For 5.2 source and 5.3 target – we have problems here.

Sorry that I can't provide any valuable info beside TRACEs.

4 TRACE logs – rollups from 5.2 to 5.2 source log and target log + rollups from 5.2 to 5.3 source log and target log.

Very quick summary:
5.2 to 5.2 on target: Entry exists in loader? true

5.2 to 5.3 on targer:
16:21:41,508 TRACE [org.infinispan.container.EntryFactoryImpl] (HotRodServerWorker-2) Exists in context? null
16:21:41,508 TRACE [org.infinispan.container.EntryFactoryImpl] (HotRodServerWorker-2) Retrieved from container null

What changed in RemoteCacheStore. What changed in HotRod? Any idea? Let me know, thank you!
