Description
DatagramSocket can be used to send multicast datagrams but surprisingly it's not possible to set the IP_MULTICAST_IF or IP_MULTICAST_TTL socket options with its setOption method. We should remove this artificial limitation so that DatagramSocket can be implemented on DatagramChannel. Removing this restriction will also simplify PlainDatagramSocketImpl.
