Pete Muir commented on WELD-904:
--------------------------------
No, they should not be enabled, but they should still be there. Just like
alternatives.
> Observer method inheritance broken
> ----------------------------------

> Key: WELD-904
> URL: https://issues.jboss.org/browse/WELD-904
> Project: Weld
> Issue Type: Bug
> Components: Events
> Affects Versions: 1.1.1.Final
> Reporter: Christian Bauer
> Priority: Minor
>
> {code}
> /*
> <beans xmlns="http://java.sun.com/xml/ns/javaee";

> <alternatives>
> <class>Foo$Bar</class>
> </alternatives>

> @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");
> }
> }
> }
> {code}
> 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:
> INIT BAR
> EVENT BAR
> One or several of these outcomes is wrong. Also, section 4.2 of the spec says
> that observer methods are only inherited if the subclass doesn't override the
> method. I'm confused why everyone (e.g.
> https://issues.jboss.org/browse/CDITCK-186) seems to assume the exact
> opposite.
