OK, I will have a look.
Out of curiosity, does the same behavior apply to Topics as well. We now know
that on queues, we need to either ack or release it. Topics are used to provide
broadcasts and I was wondering if the same applies to it. Broadcasts never come
with uniqueAppID since these are unsolicited. Hence, selector logic wont apply
to it anyways. So, if I ack the message, will that mean other instances might
not receive them?
I noticed that (as you rightly pointed), releasing them brings it back to out
receiver many times which is not ideal.
Best Regards,
Rahul

Subject: Re: QPID C++ Queue handling
Its hard to say much without knowing exactly what you did, the linked thread
has a few different things in it.
The error suggests you are using Artemis and it is trying (and failing due to
permissions) to create an Address, which I wouldnt really expect if you are
consuming from an already known response queue, one that I would assume already
existed.
You might need to ensure the broker actually treats the things as being an
'anycast' queue and treats the consumer as a regular queue consumer, as I know
Artemis typically defaults to treating things as 'multicast' for more
topic-like behaviour, which might be a problematic if you have different
consumers with different selectors.
You can do that either by ensuring the address+queue definition is anycat, or
changing the broker side address settings [1][2] so anything auto-created is
considered 'anycast', or you could alternatively add a 'queue' type hint into
the consumer by setting the type option into the consumer address string when
creating the receiver (from other threads I think "my-queue; { node:{ type:
queue }}" is the format of that).
