Thread Pool improvements on the client -------------------------------------- Key: JBAS-1338 URL: http://jira.jboss.com/jira/browse/JBAS-1338 Project: JBoss Application Server Issue Type: Task Security Level: Public(Everyone can see) Components: JMS service Affects Versions: JBossAS-4.0.1 Final, JBossAS-3.2.7 Final Reporter: Adrian Brock The thread usage on the client needs to be improved. The users of threads are: 1) The invocation layers for message delivery 2) The message listeners to wait for messages These should be combinded to use a single thread pool. There is no need for a message listener to hold a thread while it is waiting for a message. It can add itself to a registry which is then used by delivery to invoke the correct listener when a message arrives. In fact, by spec the listeners should register themselves with the session and the session deliver the messages (single threadedly - is that a word? :-).
