They will if you use persistent messaging and you don't consume all
the messages on a queue/topic, then on restart you recreate your
consumer - or you specify them on startup the next time...

FWIW using a destination from Session.createQueue() /
Session.createTopic() to send/consume messages has the same effect as
creating the destination via JMX.

i.e. the broker only allocates resources for new destinations when
they are actually used by a producer / consumer.
