> Several {{Range}} constructors call {{Range.beforeStartKey()}}, which is not final. This
is dangerous:
> bq. The superclass constructor runs before the subclass constructor, so the overriding
method in the subclass will get invoked before the subclass constructor has run. If the overriding
method depends on any initialization performed by the subclass constructor, the method will
not behave as expected.  ??Item 17, Effective Java Vol. 2, Bloch??
> If {{beforeStartKey()}} cannot be made final, the code should be refactored to make the
constructors safe.
