I have the following Producer class:

@RequestScoped
public class MsmEntityManagerProducer {

    @PersistenceContext(unitName = MSM)
    private EntityManager entityManager;

    private static final String MSM = "MSM";

    @Produces
    @MsmQualifier
    public EntityManager getMsmEntityManager() {
        return entityManager;
    }
}

which is used in a class that should execute on JBoss startup:

@ApplicationScoped
public class StartupActiviti {

    @Inject
    @MsmQualifier
    private EntityManager entityManager;

    public void init(@Observes @Initialized(ApplicationScoped.class) Object startupObject){
    }

    @PostConstruct
    public void updateTasks() {
        log.debug("start StartupActiviti");
    }
}

However, the updateTasks() method is not called and silently ignored without any exception. Well, I have found a solution (either change @RequestScoped to @Dependent or retrieve the EntityManager within the @PostConstruct method instead of injection, but does anybody has an explanation for this weird behaviour? Such kind of failures are really hard to track down if no exception is raised
