Description

I've been asked to create an issue about this, see:

http://activemq.2283324.n4.nabble.com/Selected-messages-not-being-passed-between-brokers-td3058921.html
http://activemq.2283324.n4.nabble.com/SOLVED-Re-Selected-messages-not-being-passed-between-brokers-td3062303.html

It would be very helpful to engineering staff if the following exception were given a description to help fix the cause:

In this case I was attempting to subscribe to a queue while also giving connection and subscription headers to make my client into a durable topic subscriber. Remove these extra headers and the error above goes away.

If it is any help, messages are created on broker A (where the log above originates) and consumed on broker B. Brokers A and B are SSL connected.
