[jira] Commented: (QPID-2930) JMS msg.getPropertyNames() method
should not return x-amqp-0-10.routing-key
[ https://issues.apache.org/jira/browse/QPID-2930?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12934472#action_12934472 ]
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");
