> In AssignmentCreator.java, one Comparator could break transitive attribute required for a Comparator implementation and the result is not correct.
> E.g. for:
> long IntPlusOne = 0x80000000L;
> [0]=2 * IntPlusOne + 5, [1] = 2* IntPlusOne + 8, [2] = 4 * IntPlusOne + 4,
> the compare results will be like:
> compare([0],[1]) = -3,
> compare([1],[2]) = 4,
> compare([0],[2]) = 1
