I am using activeMQ 5.10 and am trying to test the broker redelivery plugin, based on the [instructions here](http://activemq.apache.org/message-redelivery-and-dlq-handling.html). I have setup the section in my config file, but now my problem is simple: how do I actually perform a test that deliberately "breaks" a message, causing the broker to redeliver it? I have a PHP consumer (Stomp) blocking until messages arrive, and deliberately does not ACK the broker, but I don't think it's enough to indicate the message processing has "failed".
What do I need to do in order to actually see the plugin in action?
