sFlow visualization works as expected. Thank you for working on the issue @Dustin Frisch

@Chandra Gorantla

Clearing the data directory and replacing the JAR did the trick. It's working now.

Thank you.

  Try Clearing /data/ folder and then replace the jar again.

Hi Dustin,

I moved the replacement JAR file to /usr/share/opennms/system/org/opennms/features/telemetry/protocols/sflow/org.opennms.features.telemetry.protocols.sflow.adapter/27.1.1/ directory. Renamed it to the existing one and ensured only one JAR file is in the system. Rebooted opennms services. Still getting the same error.

Thank you.

I've updated the uploaded jar with the one build by CI. Please ensure that only the one in opennms/systems... exist.
