Conversation correlation id's are generated on a per thread basis.

The same controlSession is shared amongst all conversations. Calls to send are therefore synchronized because JMS sessions are not multi-threaded.

CRC Card
Responsibilities	Collaborations
Associate messages to an ongoing conversation using correlation ids.
Auto manage sessions for conversations.
Store messages not in a conversation in dead letter box.

        Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

        ConversationFactory.Conversation conversation = conversationFactory.startConversation();


        connection.start();


        // Broadcast the compulsory invitation to find out what clients are available to test.
