java.io.FileNotFoundException during Directory.copy
---------------------------------------------------

                 Key: ISPN-690
                 URL: https://jira.jboss.org/browse/ISPN-690
             Project: Infinispan
          Issue Type: Bug
          Components: Lucene Directory
    Affects Versions: 4.2.0.ALPHA2, 4.1.0.Final
         Environment: Win32 JRE 1.6.0_21-b07
            Reporter: Paul Nardone
            Assignee: Manik Surtani
         Attachments: InfinispanLuceneTest.java

I've been experiencing this error in an application I am developing and finally tracked it down to a more simple case


The stack trace is 

java.io.FileNotFoundException: Error loading medatada for index file: _0.cfs|M|test1
	at org.infinispan.lucene.InfinispanDirectory.openInput(InfinispanDirectory.java:262)
	at org.apache.lucene.store.Directory.copy(Directory.java:221)

The actual cause of this error appears to be an issue with DistributedSegmentReadLocker

During org.infinispan.lucene.InfinispanIndexInput.close(),   readLocks.deleteOrReleaseReadLock() is called.  

When eviction is enabled it appears the FileReadLockKey for the .cfs file is being evicted, as SKIP_CACHE_STORE is specified null returns for the lock which causes DistributedSegmentReadLocker to proceded to delete the actual .cfs file

When a later step tried to access the file it no longer exists resulting in the fileNotFoundException
