I understand your point, and that's why I countered with my String and
StringBuilder points. Those two classes are used underneath the covers
for inline concatenation, but, again, java.util.Objects has grander
intentions than string concatenation. This class is for all objects,
and however String/StringBuilder work with nulls is totally irrelevant
to how this class should behave. You are taking one use from one class
and making it the utility behavior for any object.
