I've been meaning to ask this for some time, but at the risk of exposing

I've looked at https://issues.apache.org/jira/browse/qpid but I can't
see how to actually raise an issue from these pages. It's not obvious to
me I'm afraid.
We're you able to get this working after registering?
Re "Personally, I'm less keen on that," with respect to qpid-route, so
what's your issue with it? As far as I can see it's a perfectly
reasonable thing to do.
In my scenario I want to be able to send messages to a fanout exchange,
have a processing consumer connect to one output queue and have a
headers exchange linked to another queue off the fanout. After
processing I want the processing consumer send its results to the
headers exchange (so the headers exchange, and thus subscribers bound to
it get both the unprocessed and processed data). Clearly I could stand
up two broker instances and federate between them, however as far as I
can see it's more efficient to link these things together on a single
broker instance.
It actually works if I comment out the two lines of code in qpid-route
and I guess if I explicitly invoked QMF methods on the broker via the
QMF API or protocol I could do it too.
It's not at all clear to me why you're not keen on this, surely it's
logically no different to federating between exchanges on different
brokers except it's more efficient.
The _purpose_ of 'federation' is to transfer messages between different
brokers; to create networks of brokers. Having a link from a broker back
to itself is a workaround for inadequacies of the internal broker
routing. I instinctively dislike this approach. It is probably simply a
matter of personal preference or taste. I see it as a likely source of
further problems.
However I'm not saying I would oppose a change that allowed the check to
be overridden, just that its not something I would use or recommend myself.
