Robbie Gemmell closed PROTON-1424.
----------------------------------
    Resolution: Incomplete

This seems likely to be due to use of one of ActiveMQ's 'transformers' which 
converts messages within the broker, or rather in some cases does not and 
simply pipes the raw protocol message bytes out as the payload of a converted 
message. Without more detail its hard to suggest anything beyond that. Feel 
free to add a reproducer.
