Hello,
I'm encountering the following exception in Jersey when sending a HTTP POST
request with multipart/mixed content using the CXF client api.
The same request succeeds when handled through CXF itself on the server side
(i.e. the method annotated with @POST with cxf MultipartBody is called
and the attachments can be accessed).

I'm not sure if this is an error on the receiving side (Jersey) or how the cxf
client is sending the request. I thought I would
check here since cxf<->cxf scenario is working and cxf<->jersey is failing.

More details below. Any ideas?
Thanks
Murali
