             Summary: Exception jitting a constaint invoking a constructor
                 Key: JBRULES-3628
                 URL: https://issues.jboss.org/browse/JBRULES-3628
             Project: Drools
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
            Reporter: Mario Fusco
            Assignee: Mario Fusco


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
