Ken Giusti resolved QPID-2482.
------------------------------
Resolution: Fixed
Ensure only one instance of a given queue appears on the routing list.
> Topic Exchange can duplicate messages.
> --------------------------------------
>
> Key: QPID-2482
> URL: https://issues.apache.org/jira/browse/QPID-2482
> Project: Qpid
> Issue Type: Bug
> Components: C++ Broker
> Environment: Linux
> Reporter: Ken Giusti
> Assignee: Ken Giusti
>
> As per Gordon's description:
> If a given queue is bound to a topic exchange with multiple bindings, a
> message sent to that exchange will result in a copy being enqueued for each
> binding that matches. This is incorrect - each message should be enqueued
> once if there is any binding to the queue that matches it.
> Steps to Reproduce:
> 1. create queue
> 2. bind it to amq.topic with two distinct bindings (e.g. red.* and *.herring)
> 3. send amq.topic a message whose routing key matches both patterns (e.g.
> "red.herring")
> 4. check the queue
> Actual results:
> The message is enqueued on the queue twice.
> Expected results:
> The message should only be enqueued on the queue once.
