'More than one post-construct method'-Exception when @PostContruct method is overloaded
---------------------------------------------------------------------------------------

                 Key: JBAS-7190
                 URL: https://jira.jboss.org/jira/browse/JBAS-7190
             Project: JBoss Application Server
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: EJB3
    Affects Versions: JBossAS-5.1.0.GA
         Environment: JBoss 5.1.0.GA, JDK6
            Reporter: Mathias Arens
            Assignee: Carlo de Wolf


I have a stateless session bean with a initialize() routine that is annotated with a @PostConstruct annotation. The intialize() routine is overloaded but the overloaded routine doesn't have a @PostConstruct annotation, like this:

@Stateless
public class AccessorBean  implements AccessorLocal {
   public AccessorBean() {
    }

    @PostConstruct
    public void initialize() {
        this.initialize(em, cache);
    }

    private void initialize(EntityManager em, Cache cache) {
        accessor = new EntityAccessorJPA(em);
        accessor.setCache(cache);
    }
   [..]
}

When I access my bean I get the following RuntimeException:

But I annotated only one routine with the @PostContruct annotation. The reason for this seams to be the overloaded initialize() routine. If I don't overload it everything is fine.

This seems to be a bug in JBoss5. Maybe the checkClass() routine in the LifecycleCallbacks class assumes that every overloaded method of a with an @PostConstruct annotated method has also a @PostContruct annotation.
