There are many examples of validation problems which are reported twice, with the same description, resource, path, location, type and also quick fix proposals. In this situation I think there is no need to obtain two identical validation errors.

Examples of such a situation:

public class Bean1() {

    public void foo(@Observes String param1, @Disposes String param2) {
		
    }
}

public class Bean2() {

    @Inject
    public Bean2(@Observes String param) {
		
    }
}
