Hi, I don't think that there will be a problem running JBoss with jrockit, since the part that decompiles the EJB's and creates the source code seem to be weblogic/appserver specific and has nothing to do with the plain underlying JVM. Apparently, JBoss is working fine in this respect - anyhow, a simple test case could be to deploy the seam samples as they are in JBoss using a jrockit JVM. Since Seam contains the TimerServiceDispatcher EJB using varargs that should trigger the problem - or not :-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4126581#...
