Milos Kleint updated MINDEXER-63:
---------------------------------

    Description: 
see issue http://netbeans.org/bugzilla/show_bug.cgi?id=219645

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:

{code:java}
public synchronized void replace( Directory directory )
     throws IOException
  {
        final Date ts = IndexUtils.getTimestamp( directory );
        closeReaders();
        deleteIndexFiles( false );
        IndexUtils.copyDirectory( directory, indexDirectory );
        openAndWarmup();
        // reclaim the index as mine
        storeDescriptor();
        updateTimestamp( true, ts );
        optimize();
 }

{code}

when deleteIndexFiles(0 fails, openAndWarmup() is not called. also 
closeReaders() ignores indexWriter..
