[weld-issues] [JBoss JIRA] Commented: (WELD-904) Observer method inheritance broken

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" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/beans_1_0.xsd"> <alternatives> <class>Foo$Bar</class> </alternatives> </beans> */ @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.
