[SNMP4J] MPv1 used with unsupported security model

[Frank Fock]

Hi Martin,

Please compare your code carefully with the examples in the JavaDoc
of the Snmp class. There are several required configurations missing in
your code. What type of SNMP request do you want to send? SNMPv1
or SNMPv3?

Best regards,
Frank
