      In this case the HATimerServiceActivator does not create any dependency against the ejb component create/start service causing a race condition:

      https://github.com/jboss-developer/jboss-eap-quickstarts/blob/6.4.x/cluster-ha-singleton/service/src/main/java/org/jboss/as/quickstarts/cluster/hasingleton/service/ejb/HATimerServiceActivator.java#L59

      .addDependency should be called there against the right ejb component.
