Add extension result in Logger ambiguous dependencies

[wuhaixing.wuhaixing.gmail.com]

exception as follow:
enviroment:
jboss-6.0.0.20100429-M3,
weld 1.0.1 final
weld extension snapshot
I created a extension class and service file in meta-inf,after deploy,jboss threw the exception:

caused by: org.jboss.weld.exceptions.AmbiguousResolutionException: WELD-001318 Cannot resolve an ambiguous dependency between [org.jboss.weld.bean-flat-ProducerMethod-org.jboss.w
ld.log.LoggerProducer.method produceLog(javax.enterprise.inject.spi.InjectionPoint), org.jboss.weld.bean-flat-ProducerMethod-org.jboss.weld.extensions.log.LoggerProducer.method
roduceLog(javax.enterprise.inject.spi.InjectionPoint)]

Is it a bug?

What was your extension class?

[wuhaixing.wuhaixing.gmail.com]

just as seam-faces's FormValidationTypeOverrideExtension,named DAOTypeOverrideExtension.

[wuhaixing.wuhaixing.gmail.com]

Qualifier DAO:

public @interface Dao {
      @Nonbinding Class<?> value() default Object.class;
}

DAO producer:

public class DaoFactory {
     @PersistenceContext EntityManager em;

     @Produces @Dao
     public Object createDao(InjectionPoint injectionPoint) throws Exception {
     
          Class<?> entityType = injectionPoint.getAnnotated().getAnnotation(Dao.class).value();
          Class<?> daoType = (Class)injectionPoint.getType();
          logger.info("create dao {}",daoType.getName());
          if (!daoType.isInterface()) {  
                       throw new UnsupportedOperationException("Only results of methods " +  
                          "which produce implementations of an interface can be replaced!");  
          }  
          GenericDao genericDao = new GenericDaoImpl(em,entityType);
          
          Object result = Proxy.newProxyInstance(  
                    daoType.getClassLoader(),  
                new Class[] { daoType },  
                new DaoInvocationHandler(genericDao));  
        
          return result;

     }
}

DAO type override extension to replace WidgetDAO with Object:

@ApplicationScoped
public class DaoTypeOverrideExtension implements Extension {
     private final Map<Class<?>, AnnotatedType<?>> typeOverrides = new HashMap<Class<?>, AnnotatedType<?>>();

        public <T> void processAnnotatedType(@Observes final ProcessAnnotatedType<T> event)
        {
           AnnotatedTypeBuilder<T> builder = AnnotatedTypeBuilder.newInstance(event.getAnnotatedType());
           builder.readAnnotationsFromUnderlyingType();
           boolean modifiedType = false;

           for (AnnotatedField<?> f : event.getAnnotatedType().getFields())
           {
              if (f.isAnnotationPresent(Dao.class))
              {
                 builder.overrideFieldType(f.getJavaMember(), Object.class);
                 modifiedType = true;
              }
           }

           if (modifiedType)
           {
              AnnotatedType<T> replacement = builder.create();
              typeOverrides.put(replacement.getJavaClass(), replacement);
              event.setAnnotatedType(replacement);
           }
        }

        public boolean hasOverriddenType(final Class<?> clazz)
        {
           return typeOverrides.containsKey(clazz);
        }

        public AnnotatedType<?> getOverriddenType(final Class<?> clazz)
        {
           return typeOverrides.get(clazz);
        }
}

DAO interface:

public interface WidgetDao extends GenericDao<Widget,Long>{
        @QuerySpecifiction("select w from Widget w order by w.name")
     public List<Widget> getWidgets();
}

usage :

private @Inject @Dao(Widget.class) WidgetDao widgetDao;

I only found org.jboss.weld.extensions.log.LoggerProducer in the repository,where is org.jboss.weld.log.LoggerProducer?

documentation about weld logger not suit for weld extension snapshot,remove the weld-logger dependency

<dependency>
         <groupId>org.jboss.weld</groupId>
