[SNMP4J] NoSuchMethodError in TestAgent

[Frank Fock]

Please believe me, the trouble is caused by the transient dependency.
You can suppress transient dependencies by using the "exclude" element
for your SNMP4J-Agent dependency which has to exclude the transient
SNMP4J 2.2.3 dependency.

Best regards,
Frank
