Unable to list root HA-JNDI bindings

Step to reproduce (using jmx-console): download a clean jboss-6.0.0-Final. go to ${JBOSS_HOME}/bin launch ./run.sh -b 0.0.0.0 -c all point the browser to http://localhost:8080/jmx-console/ open MBean service=JNDIView invoke list method. The results will be 500 - An error as occurred. The console output will be: 23:16:31,494 ERROR [org.apache.catalina.core.ContainerBase. [jboss.web] . [localhost] . [/jmx-console] .
