possible NPE in DistributedSegmentReadLocker

{code}
java.lang.NullPointerException
	at org.infinispan.lucene.readlocks.DistributedSegmentReadLocker.realFileDelete(DistributedSegmentReadLocker.java:184)
	at org.infinispan.lucene.readlocks.DistributedSegmentReadLocker.deleteOrReleaseReadLock(DistributedSegmentReadLocker.java:109)
	at org.infinispan.lucene.InfinispanDirectory.deleteFile(InfinispanDirectory.java:213)
	at org.apache.lucene.index.IndexFileDeleter.deleteFile(IndexFileDeleter.java:578)
{code}

this is caused by this code:

{code}
final int bufferSize = file.getBufferSize();
if (file != null) //during optimization of index a same file could be deleted twice, so you could see a null here
......
{code}
