I read through the javadoc again and I think it looks good.

On the implementation then Sergey has a point, the requireNonNull isn't 
needed to check b when b.length is used on the next line. One other nit 
is that the "overridden for efficiency" comment between @Override and 
the method declaration is a distraction. I don't think the comment is 
needed or just put it on the same line or above the @Overview so it 
doesn't get in the way.

The NullXXX tests can be converted to TestNG unit tests if you have cycles.
