JBoss AS 6.0.0 M3 will have that. M3 release activities are in progress and will be available this month (that's the plan). If you want to test it out before M3 is released, then you can download the latest nightly build of AS trunk from here http://hudson.jboss.org/hudson/job/JBoss-AS-6.0.x/lastSuccessfulBuild/artifact/JBossAS_6_0/build/target/jboss-6.0.x.zip
