[SNMP4J] Reception of traps not working for me.

[Frank Fock]

The targetAddress variable is never used, so you do not assign
a port (and address) to the listener. Without a port and address,
SNMP4J choses all local host addresses and an arbitrary port
 > 1024. If you guess (and use) that port by the trap generator,
you will receive it.

Frank
