[SNMP4J] Unsupported PDU type

[Yuri Krysko]

Thank you Frank! I thought of it as well. It looks like one of the SNMP
clients that I am listening for traps from is badly implemented. Is there
any way to ignore this message and/or force snmp4j to process the trap as
SNMPv1 if the client sends such rogue messages?

I used wireshark to sniff communications between my IDE and remote SNMP
client, and I can confirm this nonsense: the trap comes as v2c, but it is
actually V1TRAP type.
