Hmm, I seem to have forgotten to select the "grant license" option on the
attachment upload screen. For the record, both versions of the patch are meant
for inclusion under the Apache License.
> Allow exceptions from a ContentHandler
> --------------------------------------
>
> Key: MIME4J-16
> URL: https://issues.apache.org/jira/browse/MIME4J-16
> Project: Mime4j
> Issue Type: Improvement
> Reporter: Jukka Zitting
> Assigned To: Norman Maurer
> Fix For: 0.4
>
> Attachments: MimeException.patch, MimeException.patch
>
>
> There is currently no good way for a Mime4j ContentHandler to indicate that
> it has failed to process a message event and that no further events should be
> generated. Compare this with for example the SAX ContentHandler interface
> that allows implementing classes to throw SAXExceptions.
> Being able to throw such processing exceptions is important for example for a
> handler that wants to incrementally store a message in a backend store like a
> relational database or a JCR content repository.
> My proposal is to add a new MimeException exception class and allow it to be
> thrown from any of the ContentHandler methods. Such a change would be
> incompatible with any parser and other classes that call the ContentHandler
> methods (even indirectly, for example through the MimeStreamParser class),
> but existing classes that implement the ContentHandler interface would not be
> affected.
