RFR[7021373]: DatagramPacket exception conditions are not clear

[Patrick Concannon]

Hi,

Could someone please review my fix and CSR for issue JDK-7021373 
'DatagramPacket exception conditions are not clear' ?

This fix updates the spec concerning the exceptions thrown by the 
constructors of the DatagramPacket class, and several methods therein.
