Galder Zamarreno updated ISPN-565:
----------------------------------

    Comment: was deleted

(was: Is not using a transaction manager a valid use case? It is cos another cache operation, even if it's a single one, might be competing for the lock. So, skipping locking means that for that single invocation no locks are acquired.)

> This issue was first encountered while using Infinispan as a Lucene store via the InfinispanDirectory as that module makes extensive use of Flag.SKIP_LOCKING, attempting to use Directory.copy on cache with cacheloader produced this error
> The issue appears to relate to org.infinispan.container.EntryFactoryImpl#wrapEntryForWriting which doesn't appear to wrap the entry if it exists in the context when locking is skipped, this results in an ImmortalCacheEntry  being returned in the org.infinispan.commands.write.RemoveCommand#perform
> Test case attached
