> In 5.x, acc / collectList preserves the order of insertion.
> That is, if A1, A2 and A3 are inserted, a collectList will return 1,2,3
> In 6.x, the order is reversed. That is, in the same scenario, a list
> with 3,2,1 is generated.
> While arguably a minor issue, collectList returns a list, that is an ordered
> collection. The reversal of the order breaks the compatibility of preexising
> applications (such as drools-mas)
