It's a bit late for a reply but I thought it could help someone else seeing that error. It should get fixed starting server with setting -Djava.awt.headless=true in JAVA_OPTS or if you want to avoid having that in your environment variables, you can modify run.sh/bat and put that in the start command. For me setting java.awt.headless is a good idea anyway. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4103961#...
