[SNMP4J] How can I deal with cable disconnect when visit table?

[Leon Li]

Thank a lot.
Besides,I encounter 2 types of timeout.
one case  is plug out cable after message sent to agent.
I will know timeout occur by TableEvent (TableEvent .getStatus() = -1);

the other case is plug out cable before message sent to agent.
It'll stopped at "counter.wait()" below.
How should I deal with this case of timeout? 

SnmpRequest.java 
public void table() throws IOException {
    .......
    counter.wait();
    .......
}

Thanks,
Leo
