Tomas Sykora commented on ISPN-3183:
------------------------------------

Not absolutely sure whether this is the proper way of testing this... but I consider this scenario should work
2 JDG 6.1.GA as source cluster, 2 latest ispn-servers with this PR as a target cluster:

08:17:19,579 WARN  [org.jgroups.protocols.UDP] (multicast receiver,shared=udp) [JGRP00010] packe08:17:19,579 WARN  [org.jgroups.protocols.UDP] (multicast receiver,shared=udp) [JGRP00010] packet from 192.168.2.103:45688 has different version (3.4.0) than ours (3.3.4); packet is discarded (received 13 identical messages from 192.168.2.103:45688 in the last 66549 ms)
t from 192.168.2.103:45688 has different version (3.4.0) than ours (3.3.4); packet is discarded (received 13 identical messages from 192.168.2.103:45688 in the last 66549 ms)

Looks like we need to deal somehow with different version of jgroups as well. What do you thing? Any simple workaround for that?

Thanks!

> 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!
