      Don't overload routines annotated with @PostConstruct. The workaround applied to the example above results in:
      @Stateless
      public class AccessorBean implements AccessorLocal {
      [...]
      public AccessorBean() {
      }

      @PostConstruct
      public void initialize()

      { this.init(em, cache); }

      private void init(EntityManager em,
      Cache cache)

      { accessor = new EntityAccessorJPA(em); accessor.setCache(cache); }

      [..]
      }

      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.
