FileCacheStore throws an IllegalMonitorStateException in FileCacheVamTest
-------------------------------------------------------------------------

                 Key: ISPN-1418
                 URL: https://issues.jboss.org/browse/ISPN-1418
             Project: Infinispan
          Issue Type: Bug
          Components: Loaders and Stores
    Affects Versions: 5.1.0.ALPHA2 
            Reporter: Dan Berindei
            Assignee: Dan Berindei
            Priority: Minor
             Fix For: 5.1.0.BETA1


If there are no expired elements the bucket will not be modified and the lock doesn't need to be acquired.
We were still releasing the lock though, leading to IllegalMonitorStateExceptions in FileCacheStoreVamTest:
