[SNMP4J] Missing First Row in Table

[Frank Fock]

Hi Phil,

Oops, yes I was a bit biased through other postings ;-)
Sorry! I agree that for the concrete example, it looks
like there is a bug in the agent, although I cannot
reproduce it with the beta 1(+) version I am using
currently.

@Jesse: What version of SNMP4J-Agent do you use?

Best regards,
Frank
