Markus Wiederkehr commented on MIME4J-72:
-----------------------------------------
I understand your concern with finalizers being the flawed thing they are. I
wanted to provide the same kind of safety net you can find in various java.io
classes. But of course this code also is from Java 1.0 and it might be better
not to imitate it.
So if you strip out the finalize parts of my patch and apply the rest it's fine
by me.
> Provide a means to dispose a Message
> ------------------------------------
>
> Key: MIME4J-72
> URL: https://issues.apache.org/jira/browse/MIME4J-72
> Project: JAMES Mime4j
> Issue Type: Improvement
> Affects Versions: 0.5
> Reporter: Markus Wiederkehr
> Assignee: Robert Burrell Donkin
> Attachments: mime4j-disposable.patch, mime4j-dispose-finalize.patch
>
>
> Currently an org.apache.james.mime4j.message.Message uses temporary files to
> store text and binary attachments of the message. Unfortunately a Message
> cannot be disposed of explicitly. Even when it eventually gets garbage
> collected the temp files continue to exist until the VM exits.
> If the VM runs for a long time and a lot of e-mails get processed this can
> become a major problem.
> For this reason I think that class Entity and interface Body should both have
> a method to dispose of the object. Multipart should dispatch a dispose-call
> to its list of body parts. A BodyPart should dispose of its body and concrete
> Body implementation such as TempFileTextBody should ultimately invoke
> delete() on the backing TempFile.
> Last but not least SimpleTempStorage$SimpleTempFile should not silently
> ignore delete-calls.
