> The constructors for {{org.apache.commons.lang3.Range}} don't play nicely 
> with abstract/derived classes. Example:
> {quote}
> abstract class AbstractComparable implements Comparable<AbstractComparable> { 
>   @Override public int compareTo(AbstractComparable o) {}
> }
> class DerivedA extends AbstractComparable {}
> class DerivedB extends AbstractComparable {}
> // compiles, and reasonable since AbstractComparable is the common parent
>  static final Range<AbstractComparable> RANGE_MIXED = Range.between(new 
> DerivedA(), new DerivedB());
> // compiles, but unreasonable to force usage of parent class
>  static final Range<AbstractComparable> RANGE_SAME_CLASS = Range.between(new 
> DerivedA(), new DerivedA());
> // compiler error
>  static final Range<DerivedA> RANGE_A = Range.between(new DerivedA(), new 
> DerivedA());
> // compiler error
> static final Range<DerivedB> RANGE_B = Range.is(new DerivedB());
> {quote}
