HASingleton deployment with Barrier dependency fails on JBoss EAP 5

Issue

• Services are deployed as HASingletons by defining a dependancy in the jboss.xml of the service:

  <depends>jboss.ha:service=HASingletonDeployer,type=Barrier</depends>
  

• Starting up a server fails to start the service correctly most of the time with the following error:

  DEPLOYMENTS MISSING DEPENDENCIES:
    Deployment "jboss.j2ee:ear=TestApp.ear,jar=Report-Weekly.jar,name=TestServiceManager,service=EJB3" is missing the following dependencies:
      Dependency "<UNKNOWN jboss.j2ee:ear=TestApp.ear,jar=Report-Weekly.jar,name=TestServiceManager,service=EJB3>" (should be in state "Described", but is actually in state "** UNRESOLVED Demands 'jboss.ha:service=HASingletonDeployer,type=Barrier' **")
