Code Review 6947677: InetAddress.isReachable() throws "java.net.SocketException:Invalid argument" on Linux if run as root

[Chris Hegarty]

Hi Michael,

On some Linuxes, when bound to the loopback interface, sendto will fail 
and errno will be set to EINVAL. When that happens, don't throw an 
exception, just return false. We already do this in the case where we 
cannot create raw sockets, i.e. when not running as root.
