> Leads to an extra activacion and execution of rule "CollectAndAccumulateRule". It doesn't matter wich order conditions have, as long as there ara an "accumulate" and a "collect".
> Expected output would be:
>     Sum: 160.0
>     Items size: 4
>     Sum: 120.0
>     Items size: 3
> But is:
>     Sum: 160.0
>     Items size: 4
>     Sum: 120.0
>     Items size: 4
>     Sum: 120.0
>     Items size: 3
