NPE using cache loader preload with Lucene directory ---------------------------------------------------- Key: ISPN-2723 URL: https://issues.jboss.org/browse/ISPN-2723 Project: Infinispan Issue Type: Bug Components: Distributed Cache, Loaders and Stores Affects Versions: 5.2.0.CR1 Reporter: Christopher Wong Assignee: Galder Zamarreño Fix For: 5.2.0.Final Attachments: infinispan.cfg.xml, infinispan.log 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. <namedCache name="LuceneIndexesData"> <clustering mode="dist"> <stateTransfer fetchInMemoryState="true"/> <sync replTimeout="50000" /> <l1 enabled="false" /> </clustering> <loaders shared="true" preload="true"> <loader class="org.infinispan.loaders.file.FileCacheStore" fetchPersistentState="false" ignoreModifications="false" purgeOnStartup="false"> <properties> <property name="location" value="/some/path/.index/data" /> </properties> </loader> </loaders> </namedCache>
