1 <p>In some situation, this compareTo or compare method returns the constant Integer.MIN_VALUE,
2 which is an exceptionally bad practice. The only thing that matters about the return value of
3 compareTo is the sign of the result. But people will sometimes negate the return value of compareTo,
4 expecting that this will negate the sign of the result. And it will, except in the case where
5 the value returned is Integer.MIN_VALUE. So just return -1 rather than Integer.MIN_VALUE.</p>
