Oleg Kalnichevski resolved MIME4J-235.
--------------------------------------
Resolution: Fixed
Fix Version/s: 0.8.0
0.7.3
The header field is supposedly valid per RFC 2231 [1] (thanks to Markus
Wiederkehr). Mime4j however does not support it (see MIME4J-109 for details).
Not much we can do about it at the moment.
I managed to find out why the NPE occurred with DOM MessageBuilder only. It
turned out FallbackBodyDescriptorBuilder in core handled Content-Type headers
with invalid (or unparseable) multipart boundary as 'text/plain' whereas
DefaultBodyDescriptorBuilder in dom would happily accept multipart bodies
without a valid boundary. I fixed the latter and applied the fix to both 0.7
branch and trunk.
Please review / re-test
