I believe that the broker is operating correctly here. The #/#
subscription is not being accepted internally, but there is currently
no mechanism to indicate a rejected subscription so the broker must
provide a positive response. That you are not seeing any messages to
that topic is an indication that you don't actually have a
subscription because the topic is invalid.
