We're upgrading snmp4j to the latest so this should be fixed. Marking as fixed.

Moved this issue to the OpenNMS project since it is a non-problem but should be addressed somehow

Markus von Rüden September 24, 2013 at 4:17 AM

DefaultUDPTransportMapping is a class within snmp4j. Therefore we may have to upgrade to a newer version.
