/**
* This test will determine that the producer flow control does not kick in.
* The original MirroredQueue implementation was causing the queue to update
* the topic memory usage instead of the queue memory usage.
* The reason is that the message memory usage instance will not be updated
* unless it is null. This was the case when the message was initially sent
* to the topic but then it was non-null when it was being sent to the queue.
* When the region destination was set, the associated memory usage was not
* updated to the passed queue destination and thus the memory usage of the
* topic was being updated instead.
