Rob Godfrey commented on QPID-7922:
-----------------------------------
[~lorenz.quack] Ah, we're back in that horrible exception handling code we were
discussing in QPID-7837 last week :-( (which more generally is covered by
QPID-7531). In particular the codec layer should be detecting a framing error,
and reporting that (with appropriate descriptive text) back to the client,
rather than "connection forced". Obviously we've also said we are going to be
more lenient than the spec here (and accept messages with no body), but for
other weird cases (two footers perhaps :-) ), we should ensure we better report
the actual error.
