Subject [jira] Created: (LUCENE-1715) DirectoryIndexReader finalize() holding TermInfosReader longer than necessary
Date Tue, 23 Jun 2009 15:10:07 GMT
DirectoryIndexReader finalize() holding TermInfosReader longer than necessary
-----------------------------------------------------------------------------

                 Key: LUCENE-1715
                 URL: https://issues.apache.org/jira/browse/LUCENE-1715
             Project: Lucene - Java
          Issue Type: Bug
          Components: Index
    Affects Versions: 2.4.1
         Environment: Sun JDK 6 update 12 64-bit, Debian Lenny
            Reporter: Brian Groose


DirectoryIndexReader has a finalize method, which causes the JDK to keep a reference to the
object until it can be finalized.  SegmentReader and MultiSegmentReader are subclasses that
contain references to, potentially, hundreds of megabytes of cached data in a TermInfosReader.

Some options would be removing finalize() from DirectoryIndexReader (it releases a write lock
at the moment) or possibly nulling out references in various close() and doClose() methods
throughout the class hierarchy so that the finalizable object doesn't references the Term
arrays.
