To enable the full stack dedup custom feature please do the following:
Resolution:
1.) Set COMPARE_REQUEST_STACK_HASH=true to the my.server.properties on the backend
2.) Set takipi.neo.request.dedup.stack=0 in the agent.properties
3.) Add com.cig.jisi.util.logging.impl.Log4JLoggerLog to the blacklist filter.
Please remember this has to be done to every new environment which you create/activate.
