      Description

      The Harmony method new DatagramPacket(new byte[], int) construct the object with '0' port number while RI with '-1'.
      It leads to different exception behavior for Harmony vs RI.

      ===================== test.java ====================
      import java.net.*;

      public class test {
      public static void main (String [] args) {
      try

      { System.out.println("getPort = " + new DatagramPacket(new byte[942],4).getPort()); }

      catch (Exception e)

      { e.printStackTrace(); }
      try { System.out.println("getSocketAddress = " + new DatagramPacket(new byte[942],4).getSocketAddress()); } catch (Exception e) { e.printStackTrace(); }


      }
