Hi. I see some applications are failing to undeploy thus blocking server shutdown when java.awt.headless is not set. As well some are having issues running without that option. One of them is hudson that fails to generate certain graphics when that option is not set. As well a user reported jboss failing to shutdown without the option - http://www.nabble.com/forum/ViewPost.jtp?post=13642773&framed=y I saw also an old question about similar shutdown issue http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3995057#... I don't know if that is just a bad application design but anyway wouldn't it be better to have that option set by default for JBoss AS? Will that generate any negative effects for other users?
