The underlying implementation looks like this:

         public java.lang.Integer getDeliveryMode() { return deliveryMode; }

So there is nothing peculiar going on there. Unless perhaps the delivery 
mode isn't set at all, in which case the above will return 'null', which 
if you tried to assign to an int would cause things to break.
