The jboss-head configuration has been changed to use the new classloader so we can see how many issues it raises and fix them. If you find an issue add it as a subtask or link here: http://jira.jboss.com/jira/browse/JBAS-5119 If this change causes you serious problems then download the previous bootstrap-beans.xml http://viewvc.jboss.org/cgi-bin/viewvc.cgi/jbossas/trunk/server/src/etc/c... and replace the one in your conf/ directory. -- xxxxxxxxxxxxxxxxxxxxxxxxxxxx Adrian Brock Chief Scientist JBoss, a division of Red Hat xxxxxxxxxxxxxxxxxxxxxxxxxxxx
