[infinispan-dev] JGroups 2.8 and Infinispan

[Manik Surtani]

One more nugget of information.  :-)

Tried this with 2.8.0.Beta1/UDP to help pinpoint the issue.

True enough, things work fine if I use UDP, in that I don't see the  
dropped messages and the tests pass.  But it still is slooow when  
compared to 2.7.0.

Cheers
Manik
