I think IBM should have taken care of this, similar to how they have taken
care of this.

2006-01-31 + %months(1) = 2006--2-28

Also,
2006-01-31 + %months(2) should be consistent with 2006-01-31 + %months(1) +
%months(1)

Adding 2 months or adding 1 month + 1 months should be same right?

I write a lot in Java, and have never came across such a problem.
