FSDirectory.openFile(String) causes ClassCastException

         Key: LUCENE-523

indexes and name the index segments consistently from one build to the next. So, after creating
and optimizing the index, I rename the files and rewrite the segments file. It would be nice
if I had an API that would allow me to say "I only want one segment and I want its name to
be 'foo'". For instance IndexWriter.optimize(String segmentName)
