Subject RE: Trouble sending a ByteBuffer to a mock
Date Wed, 11 May 2016 16:32:04 GMT
Closing the loop on this... the issue ended up being that when the Exchange got to the end
of the route and went back to the 'from' (which was a cxfrs REST point) that piece complained
about the ByteBuffer. In my case the solution ended up being adding another processor after
the "end" to set up a Response for REST.
