Requirement: subscriber.durable

If a client needs to receive all the messages published on a topic, including the ones published while the subscriber is inactive, it uses a durable TopicSubscriber. JMS retains a record of this durable subscription and insures that all messages from the topic's publishers are retained until either they are acknowledged by this durable subscriber or they have expired.
