The finalize() thing does not work correctly, as the reader holds still references to other stuff when not explicitely closed. As it references them, the finalizer() is never called, as it is not to be gc'd.
You must close the reader explicit, that's all. So just close it afterusing. With Near Realtime Search, you normally get an IR, then wrap it with IndexSearcher, do your search, and close it after that. You can even call writer.getReader() from different threads, refcounting will close the readers correctly. So for each request, take a new one and close after usage.
