> If the constraint invokes a constructor with a primitive type as argument but passing the corresponding class type to it as in the following example:
> class Person {
>     public Integer getAgeAsInteger() { return age; }
> }
> rule R1 when
>    Person( new Integer( ageAsInteger ) < 40 )
> then
> end
> when the constraint is jitted the following Exception is thrown:
> java.lang.RuntimeException: Exception jitting: new Integer( ageAsInteger ) < 40
