[SNMP4J] ACM-MIB and SNMPwalk.

[Matthias Wiesmann]

I have noticed that the TestAgent that comes with version 1.0 alpha 2
fails with a simple SNMP walk in the ACM-MIB. Basically, OIDs fail to
increase at the end of the MIB.

The problem occurs on both Mac OS X and Linux.

Is there a way to address this?

How to get the problem
===================

1) start the agent java -cp SNMP4J.jar:.:log4j-1.2.9.jar
org.snmp4j.agent.test.TestAgent 127.0.0.1/1616
2) do a snmpwalk: snmpwalk -v 1 -c public 127.0.0.1:1616 .
