> I guess this is a bug - division of int fields in when part cannot be compared to double.
> For example with class A having two int fields following rule does not work
> when
>   $a: A(a == 1, b == 2, a / b < 0.99)
> but this works:
> when
>   $a: A(a == 1, b == 2, a / b < 1.0)
> Result of same expresson printed to output - System.out.println($a.a / $a.b) gives correct result of type Double.
> Why does it not work in when part?
