> for some reason (unknown to me yet) the index files cannot be deleted. The
> codebase then gets into bad state.
> possibly wrong code in DefaultIndexingContext:
> public synchronized void replace( Directory directory )
> Â Â Â Â throws IOException
> Â Â {
> Â Â Â Â final Date ts = IndexUtils.getTimestamp( directory );
> Â Â Â Â closeReaders();
> Â Â Â Â deleteIndexFiles( false );
> Â Â Â Â IndexUtils.copyDirectory( directory, indexDirectory );
> Â Â Â Â openAndWarmup();
> Â Â Â Â // reclaim the index as mine
> Â Â Â Â storeDescriptor();
> Â Â Â Â updateTimestamp( true, ts );
> Â Â Â Â optimize();
> Â Â }
> when deleteIndexFiles(0 fails, openAndWarmup() is not called. also
> closeReaders() ignores indexWriter..
