That is just a bad configuration of the jmx name as it is the same as the bean name: | <bean class="org.jboss.system.BarrierController" | name="jboss.ha:service=HASingletonDeployer,type=BarrierController"> | | <annotation>@org.jboss.aop.microcontainer.aspects.jmx.JMX(name="jboss.ha:service=HASingletonDeployer,type=BarrierController", exposedInterface=org.jboss.system.BarrierControllerMBean.class, registerDirectly=true)</annotation> | I checked in a change to set the jmx name to jboss.ha:service=HASingletonDeployer,type=BarrierControllerMBean.
