It's been a while since I've looked at the JMX beans, but I believe that each topic consumer has its own MBean somewhere in the tree, with individual per-consumer stats. Are those increasing even though the topic is not?
And for that matter, do you have at least one consumer connected and consuming messages from the topic? If there are no consumers, messages produced to the topic are immediately discarded and I don't know if that's done as an enqueue-dequeue or as a no-op but I suspect the latter, which would explain what you're seeing.
