Observer method inheritance broken
----------------------------------

                 Key: WELD-904
                 URL: https://issues.jboss.org/browse/WELD-904
             Project: Weld
          Issue Type: Bug
    Affects Versions: 1.1.1.Final
            Reporter: Christian Bauer
            Priority: Minor

@ApplicationScoped
public class Foo {

    public static void main(String[] args) {
        WeldContainer weld = new Weld().initialize();
        weld.event().select(MyEvent.class).fire(new MyEvent());
    }

    static class MyEvent {
    }

    @Qualifier
    @Target({FIELD, PARAMETER})
    @Retention(RUNTIME)
    public @interface SomeQualifier {
    }

    @PostConstruct
    void init() {
        System.out.println("INIT FOO");
    }

    void onEvent(@Observes MyEvent e) {
        System.out.println("EVENT FOO");
    }

    @Alternative
    @Specializes
    static public class Bar extends Foo {

        @Override
        void init() {
            System.out.println("INIT BAR");
        }

        @Override
        void onEvent(@Observes @SomeQualifier MyEvent e) {
            System.out.println("EVENT BAR");
        }
    }

}

The expected output is:

INIT BAR

The actual output is:

INIT BAR
EVENT BAR

Removing the @SomeQualifier annotation on the Bar#onEvent() method results in:

INIT BAR
EVENT BAR
EVENT BAR

Removing also the @Observes annotation on the Bar#onEvent() method results in:
