[SNMP4J] SNMP4j duplicate registration exception

[Frank Fock]

Hello Leonard,

SMI forbids the registration of an OID below another OID (instance 
within instance)
and obviously that makes sense. Otherwise, the lexicographic ordering
of objects in an agent could not be implemented without ambiguities.

In your case, the corresponding SMI MIB would have an error and should not
pass a proper syntax check.

Best regards,
Frank
