[infinispan-dev] [patch] Unit test to highlight potential performance and cache eviction issues in distributed mode

[Juha Heljoranta]

Hi,

In case the my previous mail didn't get through I'd still hope to get my patch 
getting merged.

The test should highlight an issue where cache.get() "fails" by taking 15 
second to execute.

When I enable trace level logging this here is what jgroups says:
14:52:36.206 [main] TRACE org.jgroups.blocks.GroupRequest - call did not 
execute correctly, request is [req_id=1260622341191
caller=nine-22069
entries:
nine-12394: sender=nine-12394, retval=null, received=false, suspected=false
nine-39772: sender=nine-39772, retval=SuccessfulResponse, received=true, 
suspected=false

I've tried to locate where things go wrong but failed to nail it down. I 
suspect that either there is some sort of race condition in infinispan or the 
bug is in jgroups.

Regards,
Juha Heljoranta
