Andrew Kennedy commented on QPID-2930:
--------------------------------------
But, why are you trying to get this property value as a String in the first
place?
This is a byte array, so I think the exception is correct in this circumstance.
If I set *any* byte array property then the code you describe will fail in the
same way. Additionally, I don't think we want to go down the road of
special-casing property names to be 'hidden' from the returned enumeration of
property names. I would think thst if a property is set, on the message, and
*can* be retreived its name should be returned.
Finally, would it be possible, instead, to fix this by setting the value as a
String in the first place? I assume this is the C++ broker, where
OutgoingMessage.cpp and IncomingMessage.cpp seem to define this as const
std::string X_ROUTING_KEY("x-amqp-0-10.routing-key");
