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(); }

}
}
