[SNMP4J] Security Issue? - Some clients work, some don't

[. .]

***Setup: I setup an SNMP Agent and populated it with 2 OIDs

***Problem:

Using one program to query the OIDs results in the correct value returned.
  OID: 1.3.6.1.4.1.318.1.1.1.2.2.1  type: snmp.SNMPInteger  value: 100

The other program throws an exception here:
                // check error status; if retrieval problem, throw 
SNMPGetException
                if (receivedPDU.getErrorStatus() != 0)
                    throw new SNMPGetException("OID " + itemID + " not 
available for retrieval", receivedPDU.getErrorIndex(), 
receivedPDU.getErrorStatus());

Exception in thread "main" snmp.SNMPGetException: OID 
1.3.6.1.4.1.318.1.1.1.2.2.1 not available for retrieval
        at 
snmp.SNMPv1CommunicationInterface.getMIBEntry(SNMPv1CommunicationInterface.java:291)

*** Both programs are querying the same OID, why does one pass and one fail?
Is there something wrong here?:
