Description
Artemis currently exposes the _AMQ_ROUTING_TYPE at least when using STOMP.
Here is what a STOMP MESSAGE frame currently looks like (header part only):
_AMQ_ROUTING_TYPE:1 content-length:1 content-type:text/unknown destination:whatever expires:0 message-id:123 persistent:false priority:4 redelivered:false timestamp:1523267009887
All the header lines are useful (and with typical lowercase names) except _AMQ_ROUTING_TYPE.
If this information can be useful to messaging clients then a more "user friendly" name should be used and documented.
Otherwise, this header should probably not be exposed, at least not by default.
