RICCARDO,
  I think you will find that this is neither an Ada nor a Java problem, but
rather a characteristic of UDP.  UDP does not guarantee delivery.  If
dropping packets is a significant issue you either need to add your own
layer of logic to retransmit packets as needed, or use TCP or some other
protocol that guarantees delivery.
