Relying on vendor specific functionality makes your application less portable between jms products. Anyway, in JBM 1.4 the scheduled delivery time is the time that the message is delivered to a queue not a consumer. This means that when you remove all messages the scheduled message does not yet exist in the queue so can't be deleted. Feel free to add a JIRA if you would like some extra management functionality added. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4192016#...
