[cdi-dev] [JBoss JIRA] (CDI-318) @WithAnnotations types can appear on any supertype

[Martin Kouba (JIRA)]

    [ https://issues.jboss.org/browse/CDI-318?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12929478#comment-12929478 ] 

Martin Kouba commented on CDI-318:
----------------------------------

Actually this is not a real issue but rather a hint for clarification.

An example:
{code}
@Target({ TYPE, METHOD, PARAMETER, FIELD, CONSTRUCTOR })
@Retention(RUNTIME)
@Inherited
public @interface Marker {
}
@Marker
public interface Foo {
}
public class Bar implements Foo {
}
{code}
and observer:
{code}
public void observeMarker(@WithAnnotations({ Marker.class }) @Observes ProcessAnnotatedType<?> pat) {
}
{code} 
I think PAT for Bar should be observed because @Marker is inherited (CDI follows JSL rules here). The question is whether this makes sense because "A bean may inherit type-level metadata and members from its superclasses", not superinterfaces.

> Is this intentional? Supertypes also include interfaces which are not very useful here as beans may inherit type-level metadata and members from superclasses only.
> Is there any special use-case for this?
