[hibernate-dev] MassIndexer have any known issues when InfinispanDirectory is used?

I'm trying to setup clustering of entities and Lucene indexes for our app with Hibernate 3.6.5, Hibernate Search 3.4.0, Infinispan 5.0. I'm using FileCacheStore for the Infinispan cache loader (InfinispanDirectoryProvider). MassIndexerImpl.startAndWait() never returns with this configuration. A lock is never able to be obtained, see the stack from a thread dump below. The same MassIndexer call works fine when using FSDirectoryProvider. Should MassIndexer work with Infinispan as the directory?
