I'm running the following code in WildFly to create an EntityManagerFactory CDI bean for application deployments to use but I don't seem to be able to use the passed bean name ("pu1") in a test that has:

"
@Inject
@Named("pu1")
EntityManagerFactory entityManagerFactoryByPuName;
"

I expect that the following container code is naming the created bean but I thought the passed name would work with @Named but it doesn't seem to.  The following EE container code (AfterBeanDiscovery callback) is doing the following which includes a call to "beanConfigurator.name(persistenceUnitMetadata.getPersistenceUnitName()):".  Should setting the bean name this way allow @Named references to the passed name ("pu1" in this case) lookup the created bean as I am showing above?

"
private void entityManagerFactory(
        AfterBeanDiscovery afterBeanDiscovery,
        PersistenceUnitMetadata persistenceUnitMetadata,
        List<String> qualifiers,
        IntegrationWithCDIBag integrationWithCDIBag) throws InstantiationException, IllegalAccessException {

    String scope = applicationScoped;

    // EntityManagerFactory setup
    BeanConfigurator<EntityManagerFactory> beanConfigurator = afterBeanDiscovery.addBean();
    beanConfigurator.addTransitiveTypeClosure(EntityManagerFactory.class);

    try {
        if (!persistenceUnitMetadata.isDuplicate()) {
            beanConfigurator.name(persistenceUnitMetadata.getPersistenceUnitName());

I added a call to "beanConfigurator.addQualifier(NamedLiteral.of(persistenceUnitMetadata.getPersistenceUnitName()))" and that seemed to help my unit test to be able to lookup the created CDI bean via "@Inject @Named("pu1") EntityManagerFactory entityManagerFactoryByPuName;"

Still, I'm curious as to what the call to BeanConfigurator.name(String) accomplishes?  
Does that make it possible to do the bean injection a different way?

Thanks,

Scott

        Class<? extends Annotation> scopeAnnotation = persistenceUnitMetadata.getClassLoader().loadClass(scope).asSubclass(Annotation.class);

                    .asSubclass(Annotation.class);
            beanConfigurator.addQualifier(ScopeProxy.createProxy(qualifierType));
        }
        Class<?> entityManagerFactoryClass = EntityManagerFactory.class;
        beanConfigurator.beanClass(entityManagerFactoryClass);
        beanConfigurator.produceWith(c -> {
                    return integrationWithCDIBag.getEntityManagerFactory();
                }
        );
    } catch (ClassNotFoundException e) {
        throw JpaLogger.ROOT_LOGGER.classNotFound(e, persistenceUnitMetadata.getScopedPersistenceUnitName());

Thanks,
