> When comparing an Integer taken from Map.get() with a String, Mvel coerces the type so they are compared as Integers.
> For example, here $map.get("key") returns Integer 5, $status is String "10". So it doesn't match (expected).
> {noformat}
> rule R when
>   FactWithMap( $map : valueMap )
>   Person( $status : status, $map.get("key") >= $status)
> then
> end
> {noformat}
> However, after jitting, the constraint is evaluated as true so the rule is fired (unexpected).
