Otis Gospodnetic resolved LUCENE-168:
-------------------------------------
Resolution: Won't Fix
Assign To: (was: Lucene Developers)
Ancient bug report. It seems like it's always on Windows platform and, from
what I can tell from various people's reports, it has to do with concurrency
rules not being followed 100%.

> Subject: Re: IndexWriter.optimize bug in version 1.3-final?
> Date: Tuesday, January 06, 2004 12:25 PM
> The source code of the method.
> It fails at ( writer.optimize();// This is where it fails), which is not
> within a try/catch.
> It works great with the lucene-1.2 version but fails with the
> lucene-1.3-final.jar
> Any ideas would be appreciated.
> Apologies for posting this question to the dev list initially.
