[SNMP4J] NoSuchMethodError in TestAgent

[Frank Fock]

Hi Etienne,

It seems that the class ed.demo.snmp4j.AgentTest had been compiled with a
different SNMP4J version than 2.2.4. But even then I agree that the behavior
is weired because the signature of the method has not changed for a very 
long
time.

Fortunately, you can (and should) now use SNMP4J-Agent 2.1.1 together with
SNMP4J 2.2.5.

Best regards,
Frank
