QPID-6768: Avoid unnecessary message payload copy during publish (0-8...0-91)
> 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
> 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 a
> 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.
