What is the version of JBoss server that Percussion is currently using?

I know that JBoss-4.2.3 GA is out of support starting this month, so I would like to check with you what version of JBoss is being used?

CM1 does currently use version 4.2.3 GA. However, we have an open project to replace JBOSS completely in a coming release. Once more details are available, I’ll be sure to keep you updated.
