Here is an overview of the issue:
---------------------------------------------------------------------
        Key: JAMES-248
    Summary: memory management - finalize/nullify after successful delivery of retrieved MailImpl
       Type: Improvement

     Status: Unassigned
   Priority: Major

    Project: James
   Versions:
             2.1.3

   Assignee: 
   Reporter: Ralf Hauser

    Created: Mon, 5 Apr 2004 11:54 AM
    Updated: Mon, 5 Apr 2004 11:54 AM
Environment: Redhat 9

Description:
My application required an adaptation of the MailRepository.retrieve() method.
It creates a temporary object on disk and I provided it with a finalize() method for cleaning
up.

The interesting thing is that this finalize is not executed until I shut-down james.
This leads me to the conclusion that even if there was no ties to a disk operation the 
  mipl.setMessage(mimeMessage);
remains in memory long after the MUA has disconnected.

Isn't this kind of a memory leak? After all, attachments to such a MIMEMessage can be 13MB
large.
Shouldn't those objects be null-ed latest after the POP3Handler.doQUIT of a session?
