Body:
Noel, thx for the insight.
But wouldn't the finalizer immediately be called if the MailImpl object the
MailRepository.java's retrieve() mehtod returns would be actively set to null once it
has been transported to the MUA?
Perhaps addint the line
mc = null;
at the end of the POP3Handler.java's doRETR() method's try-catch block would aready do
it?
perhaps do it again in a finally part to this try-catch block?

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

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?
