      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.

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
