I use a MDB as a durable subscriber to a topic. Is there a way to make sure my MDB is started before I put any messages on the topic, so that I am sure no messages are lost? Currently I am using 'conection.start()' in my '@PostConstruct'-method, but if some messages are put on the topic imediately at startup they are lost, I have to wait a second os so before putting any messages on the topic.
