> I am seeing an NPE that looks a lot like ISPN-1470, except this is happening in version 5.2.0.CR1 of Infinispan. I have configured Infinispan's Lucene directory provider for use in Hibernate Search. The Hibernate SessionFactory is configured with a JTA transaction manager. Starting with no index works fine, but if I shut down Tomcat (with shutdown.sh) and restart, a huge pile of exceptions occur, starting with an NPE. The cache configuration in infinispan.cfg.xml looks like the following. I will attach a log file excerpt with a sampling of the exceptions being logged. This only happens with distributed mode. Replicated mode is fine. I have seen this happen with both the Jdbm and file cache store.
