I've set up JBoss 7.1.0.Final as a fresh installation and started standalone

I can successfully connect with regular jconsole or $JBOSS_HOME/bin/jconsole. In the MBeans tab, I can see various subtrees, including jboss.as

Then I stop JBoss and add the jmxetric monitoring agent, as described here:

Now, with JBoss running with jmxetric, I connect to it with jconsole (either regular jconsole or $JBOSS_HOME/bin/jconsole) and I can see all the same subtrees, except one, jboss.as is missing. I can see jboss.modules, jboss.ws, jboss.msc, jboss.jta and core JVM subtrees
