[classlib][net] compatibility: incorrect default port number for new DatagramPacket(new byte[],
int)
----------------------------------------------------------------------------------------------------

                 Key: HARMONY-890
                 URL: http://issues.apache.org/jira/browse/HARMONY-890
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Vladimir Ivanov


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();
       }                  
    }
}
