Vladimir Blagojevic commented on ISPN-1160:
-------------------------------------------

I think it would make our life easier TBH. HAving both options working would be great! This issue is unrelated to FLUSH protocol per se but related to how digests are calculated in presence/absence of FLUSH. I'll investigate this on JGroups level.

> I was testing with a replicated cache in infinispan.  And in an attempt to try it in 5.0CR4 I have found that I cannot use a replicated or invalidating cache (async or sync) that has fetchInMemoryState set to true unless I have FLUSH protocol provided with udp.  I was able to reproduce this using the distributed jgroups-udp.xml file, which has FLUSH removed.  When I tried with jgroups-tcp.xml it works without the FLUSH protocol as expected.
> I have attached the test java file that is only using infinispan and is very basic that reproduces it every time I try.  I also will attach the log file from both the coordinator and the joining peer that shows this issue.
