Yes, that's the outlier I mentioned in the reply (that usage should 
probably be changed anyway as the send shouldn't be create a SocketAddress).

Maybe. We normally default to specifying the long standing behavior but 
there are cases where the risk of fixing an issue is very low, e.g 
DatagramSocket.send was changed recently to throw IAE for a case that 
was previously unspecified and where the implementation threw an 
accidental NPE.
