Bryan Kelly commented on ISPN-2981:
-----------------------------------

I have started consumption of infinispan with hibernate search today.  Hibernate search version 4.5.0.Final which is dependent on infinispan 6.0.2.Final.  The stack trace that we get is very similar to the one reported here.  The configuration is similar other than we are using JGroups + TCP and stock infinispan configuration.  We have a JMS setup to process index changes.  When we run a single threaded test everything replicates find.  However, when we run a test with 6 threads that purpose writes / changes to the index we get the stack trace above.

> I have been trying to use Infinispan as a Lucene directory provider under Hibernate Search. A single node writes to the index via JMS. A configuration that uses Infinispan in distributed mode seems to work under development, but under load results in an exception that looks like the following.
