Atm. it is not clearly defined what the expected behaviour is in case of hidden fields and getters. A member is hidden, if it is private and a sub-class defines another member with the same name:

public class Base {

    @Size(min=3)
    private String value;
}

public class Sub extends Base {

    @Min(3)
    private Long value;
}

For validate() it seems reasonable to validate the constraints on both "value" members. But what should happen for validateProperty() (validate both, only Sub#value? Should there be a way to only validate Base#value? Similarly for validateValue(), which has the additional challenge that the allowed types may differ.
