A trivial dependency on the ServiceController as illustrated by this mbean service fragment:

<mbean code="org.jboss.jmx.util.NotificationGroup"
name="jboss:service=NotificationGroup">
<!-- The service controller injection -->
<depends optional-attribute-name="ServiceController"
proxy-type="attribute">jboss.system:service=ServiceController</depends>
</mbean>

fails because the ServiceController controller does not actually register itself as an available service.
