Keith Wall updated QPID-6768:
-----------------------------
Description: The
{{org.apache.qpid.framing.ContentBody#writePayload(java.io.DataOutput)}} method
(on the client's publish path when using 0-8..0-91) always copies the payload
before writing to the {{DataOutput}}. The underlying byte buffer is expected
to be a heap byte buffer and so will have a backing array, so the copy can be
optimised away in this case. (was: The
