[SNMP4J] Missing First Row in Table

[PHIL BERGSTRESSER]

Frank, I believe Jesse is correct. getNext, getBulk should return
exactly what YOU say they should: the NEXT OID in lexicographical order,
which if the last index is not supplied, would be 12 in his case. You
state the technology correctly, but don't see his example correctly. The
Next instance after myOid.indexOid is myOid.indexOid.12. This is usually
an agent bug. Think about it.

Hello Jesse,

The behavior you described is intended and not a bug.
GETNEXT and GETBULK return the next accessible object instance with an
OID (lexicographic) greater than the OID specified in the request.

To get also the instance for the OID you have in mind, you can use
OID.predecessor() as the starting OID.

Best regards,
Frank
