Rob Godfrey resolved QPID-6768.
-------------------------------
    Resolution: Fixed

> Avoid unnecessary message payload copy during send (0-8...0-91)
> ---------------------------------------------------------------
>
>                 Key: QPID-6768
>                 URL: https://issues.apache.org/jira/browse/QPID-6768
>             Project: Qpid
>          Issue Type: Bug
>          Components: Java Client, Java Common
>            Reporter: Keith Wall
>            Priority: Minor
>             Fix For: qpid-java-6.0
>
>
> 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.
