JSR-250 PFD recommends the following guidelines for how annotations interact with inheritance in order to keep the resulting complexity in control:

1. Class-level annotations only affect the class they annotate and their members, that is, its methods and fields. They never affect a member declared by a superclass, even if it is not hidden or overridden by the class in question.
2. In addition to affecting the annotated class, class-level annotations may act as a shorthand for member-level annotations. If a member carries a specific member-level annotation, any annotations of the same type implied by a class-level annotation are ignored. In other words, explicit member-level annotations have priority over member-level annotations implied by a class-level annotation.
3. The interfaces implemented by a class never contribute annotations to the class itself or any of its members.
4. Members inherited from a superclass and which are not hidden or overridden maintain the annotations they had in the class that declared them, including member-level annotations implied by class-level ones.
5. Member-level annotations on a hidden or overridden member are always ignored.

Throws:

IntrospectionException
