Comment 30 for bug 1178375

I concur with Ken's comment above (i.e. #26). The topology 2 'TopicConsumer' does not set a link name which means each consumer will be independent (non-competing). That's fine where it is for the topic with server name appended, but *not* when it is for the topic itself, when it needs to in fact be a shared subscription between all servers on the topic.

See https://review.openstack.org/59677 also, which changes the setting of link name for topology 1. Doing the same thing in topology 2 (or better, pulling the line that conditionally sets the link name into the common path) would fix the problem as described by Ken.
