Body:
Explicit nulling objects can do exact opposite you intend, i.e., it can make the JVM
less efficient at garbage collection.

Here is an overview of the issue:
---------------------------------------------------------------------
Key: JAMES-248
Summary: memory management - finalize/nullify after successful delivery of
retrieved MailImpl
Type: Improvement
Status: Closed
Priority: Major
Resolution: CANNOT REPRODUCE
Project: James
Versions:
2.1.3
Assignee:
Reporter: Ralf Hauser

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?
