Missing Dependency error when starting JBoss 5.1

Issue

• Get the following error on startup, which does not seem to effect anything up I am hoping to resolve this:

    Dependency "jboss:service=invoker,type=jrmp" (should be in state "Create", but is actually in state "** NOT FOUND Depends on 'jboss:service=invoker,type=jrmp' **")
  Deployment "jboss.jmx:name=MBeanProxyRemote,protocol=jrmp,type=adaptor" is missing the following dependencies:
