test(java-oracle): ArpRun records ARP as Java FILIUS runs it

Browse Source 
Sends to addresses no card has on the new arp-routed network (ping on the
LAN and behind a router, two UDP datagrams, one behind a failing one):
frames and calls. ScenarioNetwork builds routers and their interfaces.

Measured: ARP asks twice, a round trip each, then host unreachable; the
thread that waits is the ping's caller, the router's IP thread, or the
node's transport thread per protocol, which blocks the next send.
