broker Health mbean doesn't seem to report error status conditions in couple cases

Was hoping to force the ActiveMQ health mbean to show some error status indicators so I've tried a couple configurations to deliberately force an error condition. For example:

1) Turn off persistence, set a low memory limit on queues (memoryLimit="512kb").

2) Enable persistence, set a low memory limit on queues and set a low limit on storeUsage and tempStoreUsage.

In either case I then start a second container with the "example-camel-mq" route running. I edited this route by replacing the producers message with bunches of Lorem Ipsum text. The context has a producer and consumer route. So to force an error condition, I stop the consumer route and keep an eye on messages coming into the queue. I see in the logging that producer flow control kicks in and the producer is halted. However when I check the health mbean in JMX (from hawtio) the status is shown as "good". Shouldn't this be indicating that a destination is blocked up?
