Missing date coercion in constraint using an instance field or a declaration

Automatic String to Date coercion is not performed in case the accessed field is not a getter method but an instance field of the class as in:

   public class Person {
       public java.util.Date date;
   }

    rule x when
       Person( date < "1-Jan-2000" )  // Error flagged here, if...
    then ...end

or when the class has proper a getter method but the constraint is expressed with a binding declaration as in:

    rule x when
         Person( $date: date, $date < "1-Jan-2000" )
    then ...end
