[SNMP4J] SNMP4j 2.2.3 / 2.2.5 bulkwalk problem

[Frank Fock]

Hi Johann,

SNMP4J works fine here. The agent does not return more than 10 repetitions
(which is fine according to the SNMP standard, the agent may at any time 
decide
to return less than the max repetitions).
Your code must be able to cope with that.
Have you seen the TreeUtils class in SNMP4J yet? It simplifies the walk 
operation
for you.

BTW, OIDs do not start with a dot. It seems the whole world is using it 
that way
although only NET-SNMP uses this non-standard notation to distinguish
"absolute" OIDs (OIDs are always absolute) from relative OIDs (which in 
fact do
not exist).

Best regards,
Frank
