Thanks I will add this observation to the GA release notes. We have this http://jira.jboss.org/jira/browse/JBMESSAGING-725, which will insure the build process fails quicky and with a self-explanatory message if ant is too old. Better yet, we should ship our own embedded ant. I don't know if this is something that is generally known, but anybody can pick an open task and send a patch for it :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4020412#...
