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.

Thanks,

Chris - is this a kernel bug where it should be returning EHOSTUNREACH
or some other error instead? It is specific to the loopback interface so
do you have the same issue when bound to a real interface?
It appears to be specific to the loopback interface. You can reproduce
the very same behavior using DatagramSocket and DatagramChannel; bind to
the loopback address and send a packet to a remote address.
I was not too happy about doing this until I found that we do the very
same thing in non raw sockets case.
