If you didn't create any queues, the message won't be kept. You'd only hit problems if you had created a queue but then never consumed the messages from it.
It's possible to configure a timeout after which inactive destinations will be deleted, if you were interested in that. http://activemq.apache.org/delete-inactive-destinations.html has details if you're interested.
