    Description

      I have a simple test case that hits this NPE:

          [junit] java.lang.NullPointerException
          [junit] 	at java.io.File.<init>(File.java:305)
          [junit] 	at org.apache.lucene.store.NIOFSDirectory.openInput(NIOFSDirectory.java:67)
          [junit] 	at org.apache.lucene.store.FSDirectory.openInput(FSDirectory.java:333)
          [junit] 	at org.apache.lucene.index.SegmentInfos.read(SegmentInfos.java:213)
          [junit] 	at org.apache.lucene.index.IndexFileDeleter.<init>(IndexFileDeleter.java:218)
          [junit] 	at org.apache.lucene.index.IndexWriter.<init>(IndexWriter.java:1113)
          [junit] 	at org.apache.lucene.index.TestIndexWriter.testNoSegmentFile(TestIndexWriter.java:4975)
          [junit] 	at org.apache.lucene.util.LuceneTestCase.runBare(LuceneTestCase.java:277)
      

      It happens if you have an aborted index, ie, there are segment files in there (*.frq, *.tis, etc.) but no segments_N file, and then you try to open an IW with CREATE on that index.
