Memory leak when using default ReaderProvider with Master/Slave Directories
---------------------------------------------------------------------------

                 Key: HSEARCH-557
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-557
             Project: Hibernate Search
          Issue Type: Bug
          Components: directory provider
    Affects Versions: 3.2.0.Final, 3.1.1.GA, 3.1.0.GA
            Reporter: Sanne Grinovero
             Fix For: 3.1.2, 3.3.0


The default ReaderProvider, org.hibernate.search.reader.SharingBufferReaderProvider is keeping a reference to an open index of the most current IndexReader, so it's able to refresh this on demand and track references to previously opened instances.
The currently open indexReaders for the not-active directory might consume a lot of memory; follows a forum reference where it appears to be a memory leak; still not sure if it's a leak or just needing twice as much memory as otherwise, please comment here.
