The use case in which we use external context to lookup a destination in remote EAP 6 instances and try to send a message to it does not work. We can create a destination and then send a message but after restarting EAP 6 the EAP 7 RA never reconnects to the remote EAP 6 instance so the MDB can't consume any messages.

I see those errors in EAP6 logs
