in ClusterConnectionBridge.beforeForward(Message message, SimpleString
forwardingAddress), we call super.beforeForward(message, null). The is why we
lose the address. This code path is executed when broker1 forwards an AMQP
message to broker2. This is why we will only see this in a cluster, when a
producer sends a message to broker1 and a consumer is listening on broker2.
