Re: openjms "receiver hang" problem

I am with the same problem. 

My code:

connection = getTopicConnection();
session = connection.createTopicSession(false,
Session.CLIENT_ACKNOWLEDGE); // never returned
Topic topic =
(Topic)getContext().lookup(SessionContext.getSession().getTopic());
subscriber = session.createDurableSubscriber(topic,
"xxxx"); 

I am using 0.7.6.1 and rmi connection.
