Subject Re: AMQ5.8.0: Strange consumer/producer dependency issue
Date Fri, 06 Sep 2013 00:54:19 GMT
Yep working as designed :) topics are broadcast destinations. They will
deliver messages to whomever is listening at the time. If you need queuing
semantics check out virtual destinations or durable subscribers. You could
also take a look at subscription recovery policy on the broker side.
