I agree with Larry on this one. IB already supports autoboxing. The real issue here is why do you have nulls in a column that is represented by a primitive? If the column is null what would you expect your returned value to be as an int/boolean?
On a second note.... Why such a push to use a primitive? In the real world 99% of the data returned from a DB is mutable and hence there is really no performance gains by using a primitive.
