I am not sure if this is a bug or not but here is a very odd behavior we have encountered with embedded vRO (from vRA 7.2). I am testing our policy setup where we have several AMQP subscriptions with each one bound to their own queues on a single direct exchange. On embedded vRO a message from single queue inexplicably triggers every single subscription. This is certainly not intended and differs from the result we typically get on a standalone vRO instance (7.1) against the same queue service setup. The intended behavior is that single queue triggers single subscription that is bound to it.
I have been able to reproduce this in my lab. Not sure if this is embedded versus standalone or version difference at this point. Was hoping to get some community feedback if anyone has encountered this situation.
