I looked into this further and even prototyped a solution, but i am
not happy with it. There is a fundamental mismatch between the Apache
HTTP client model and that supported by MessageBodyWriter that is hard
to resolve without doing some sort of hack.
The only thing that comes to mind is to calculate the boundary string
when an instance of MultiPart is created. This obviously precludes a
MultiPart instance embedding itself (which would not be possible
anyway at the moment because it would blow the stack up).
Could you log an issue?
Thanks,
