Lucene Directory's methods length, filemodified, touch should return 0L instead of FileNotFoundException for unexistent fils
----------------------------------------------------------------------------------------------------------------------------

                 Key: ISPN-625
                 URL: https://jira.jboss.org/browse/ISPN-625
             Project: Infinispan
          Issue Type: Bug
    Affects Versions: 4.1.0.CR3
            Reporter: Sanne Grinovero
            Assignee: Sanne Grinovero
             Fix For: 4.1.0.Final, 5.0.0.BETA1


Lucene appears to be inconsistent on this behaviour; the FSDirectory documents a FileNotfoundException but actually returns 0 while the RAMDirectory implements the FileNotfoundException but is totally synchronized,
I assume the FSDirectory is more reliable in this case and we got a reported error about this, my rationale is that the race condition which FSDirectory can handle is never an issue in the synchronized blocks of RAMDirectory.

Inspecting the code of Lucene, there appears to be no harm done in returning 0 for unexistend metadata.
