Regis Xu commented on HARMONY-6412:
-----------------------------------

I ran the test with RI6 got:

Exception in thread "main" java.lang.IllegalArgumentException: unresolved address
	at java.net.DatagramPacket.setSocketAddress(DatagramPacket.java:295)
	at java.net.DatagramPacket.<init>(DatagramPacket.java:123)
	at java.net.DatagramPacket.<init>(DatagramPacket.java:158)

RI changed behavior between java5 and java6, and  IllegalArgumentException is more clear and reasonable for me, so I think we can just follow java6. What do you think?

> [classlib][luni]DatagramSock do NOT throw Exception
