DefaultMethodsInAnnotations.java

Consider the following annotation

@Qualifier
public @interface ConfigProperty {
    @Nonbinding
    String value() default "";
}


If I like to programmatically create an annotation instance then I can write

    private static class ConfigPropertyLiteral extends AnnotationLiteral<ConfigProperty> implements ConfigProperty {
        @Override
        public String value() {
            return "";
        }
    }

Now what happens if later (in a spec change) some attributes gets added?
E.g.
@Qualifier
public @interface ConfigProperty {
    @Nonbinding
    String value() default "";
  
    boolean mandatory() default true;
}

After this change my ConfigPropertyLiteral blows up as it doesn't implement the mandatory() method!
  
Is there a way to declare default methods on annotations? Not as far as I know...
