Error description

Found memory leak. Determined memory leak is from spawned user
threads
Local fix Problem summary
****************************************************************
* USERS AFFECTED: WebSphere Application Server, Version 5 *
* users of the J2C Connection Manager (this *
* includes users of Version5 DataSources, J2C *
* Connection Factories, and JMS Connection *
* Factories). *
****************************************************************
* PROBLEM DESCRIPTION: A Java.lang.OutOfMemoryError is thrown, *
* or excessive memory is taken up by *
* WebSphere Application Server, from an *
* application that spawns its own *
* threads. *
****************************************************************
* RECOMMENDATION: *
****************************************************************
If an application spawns its own threads and accesses a resource
( JMS, J2C, or JDBC ) in those threads, it is possible for the
connection handles to leak, eventually causing an
OutOfMemoryError exception.
Problem conclusion
Added nullContextHandles (list of handles that were opened or
closed when no HandleList was present on the thread), this is
checked first - before OrphanedHandles, and has resolved the
issue).
