             Summary: NPE using cache loader preload with Lucene directory
                 Key: ISPN-2723
                 URL: https://issues.jboss.org/browse/ISPN-2723
             Project: Infinispan
          Issue Type: Bug
            Reporter: Christopher Wong
            Assignee: Mircea Markus
         Attachments: 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>
