Re: problem:lucene did not delete old index file after optimize method called

[Michael McCandless]

My guess is there is accidentally still a reader open, at the time
that IW tries to delete these unreferenced files.

Eg if you close & reopen your reader, always, then there is always a
reader open on the index.

Try closing all readers, then close IW, then open & close a new IW,
and see if the files are deleted.

Or... can you make this happen in a small test case?
