> AbstractRangeValidator has the following Signature:
> public abstract class AbstractRangeValidator<R extends Comparable<R> & Serializable, V extends Serializable> extends Behavior implements IValidator<V>
> Because of this it cannot be used with DateMidnight as its Comparable implementation is in a base class.
> I think the correct signature should be:
> public abstract class AbstractRangeValidator<R extends Comparable<? super R> & Serializable, V extends Serializable> extends Behavior implements IValidator<V>
