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.
