The ordering only applies to normal redelivery (i.e. not delayed). Guaranteeing ordering with a delayed redelivery would be even more complicated since we'd have to block any other messages that arrived in the intervening period being delivered. It is possible though - you could add a feature request if you like :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4104466#...
