Generic producer broken with Weld 2

[alberto_souza]

I have a producer that produces List for injection. It is a workaround to keep compatibility with Spring, the DI provider that was used. To keep in touch with the weld2, i updated my jboss version and the factory stoped to work. Any ideas? Here is my code:

[java]

@Produces

          public List producesList(InjectionPoint injectionPoint){

                    ParameterizedType type = (ParameterizedType) injectionPoint.getType();

              Class klass = (Class) type.getActualTypeArguments()[0];

              Set<Bean<?>> beans = beanManager.getBeans(klass);

              ArrayList objects = new ArrayList();

              for (Bean<?> bean : beans) {

                                   objects.add(beanManagerUtil.instanceFor(bean));

                         }

                    return objects;

          }

[/java]

Weld 2 is more strict and does not allow this usage (using raw types of a class with type arguments). Instead, you should use a type variable. The signature of your producer method would look like this:

public <T> List<T> producesList(InjectionPoint injectionPoint){

Note that it's currently being discussed by the expert group whether the non-generic declaration should be supported or not. You can find more information here: https://issues.jboss.org/browse/CDI-304

Thanks Jozef!. I saw the discussion... In my opinion the raw type should work like the old version . I do not see any advantage using this new approach
