This is a low-level socket error that is occurring when JCIFS is
simply trying to create a socket. If 1.1.11 worked, then the problem
is probably that this "Alx OS" whatever that is is only listening on
port 139 and dropping packets on port 445. Normally if a
ConnectException or NoRouteToHostException occurs, JCIFS will retry on
port 139 but since it's just a SocketException and a timeout there's
not much we can do about catching that and retrying.

Try setting jcifs.netbios.hostname = WHATEVER. One artefact of setting
this property is that it forces the use of port 139. It's a bit of a
hack but it should work.
