In the case of Socket/ServerSocket, the bind and connect methods specify 
IAE when the SocketAddress is not supported. For 
SocketChannel/ServerSocketChannel, UnsupportedAddressTypeException (a 
specific IAE) is specified. So I think we are okay on this point.

I assume you mean the protected connect(String, int) method on 
SocketImpl. Need to check but I think this may be limited to the case 
where Socket's connect(SocketAddress) is called with an unresolved 
address. But yes, the impl would need to do an InetAddress.getByName and 
choose an Inet4Address or Inet6Address to match the protocol family. As 
regards the spec then maybe we should separate this from this JEP as it 
would mean clarifying the spec of a standard API.
