Greetings!
I've encountered an exception when trying to configure AMQ-A during a bit of exploratory/PoC work I'm doing around clustering.
I'm making this report mostly on the basis that I haven't been able to infer any cause or course of action from the exception messages. Even if this is a result of a misconfiguration, perhaps the feedback can be improved to make it easier to troubleshoot?
I have already collated the details over at a question of Stack Overflow, which I've also attached as an external issue URL.
