[SNMP4J] Agent/ProxyForwarder - Invalid response message when wrong contextEngineID is used

[Senthil Muniswamy]

Frank,

If a wrong contextEngineID is mentioned, the Agent w/ ProxyForwarder sends
an invalid response message. Actually, the ScopedPDU contains wrong type
(Integer32) for the contextEngineID.

java.io.IOException: Wrong ASN.1 type. Not a string: 2 at position 3
