By TomyLobo:

Shouldn't this return 0?
Otherwise this violates an important compareTo criterion:
a > b <=> b < a
(a.compareTo(b) > 0) == (b.compareTo(a) < 0)

If a and b have the same priority here, both compareTo calls will return 1 and the criterion is violated.

However, since this was explicitly changed from what I perceive as correct to the current state, I'm going to leave sk89q some time to comment before I mess with it.
