[SNMP4J] Missing First Row in Table

[Frank Fock]

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
