Subject RE: ParallelMultisearcher

Hi Ganesh, It's definitely in 3.0.3:

  @Override
  public void close() throws IOException {
    executor.shutdown();
    super.close();
  }

This code is in the downloaded .src.zip file of Apache Lucene 3.0.3. Are you
sure that you call close() on the ParallelMultiSearcher (e.g. when you are
done with it or reopen your indexes)? In contrast to Lucene 2.9, PMS uses
Java 5's Executors to manage thread pools of workers. The threads are only
shutdown on ParallelMultiSearcher.close().

The entry is missing in Changes.txt, it somehow was merged with the other
PMS issue there, that was my fault, sorry (I am the release manager of 2.9
and 3.0).
