I want to integrate a Scala app (Kestrel, http://robey.github.com/kestrel) with NewRelic using java agant but failed with error

sh scripts/devel.sh 
Starting kestrel in development mode...

Steps to reproduce:

  • Download http://robey.github.com/kestrel/download/kestrel-2.4.1.zip
  • Put newrelic.jar & newrelic.yml (with config) inside another folder, e.g. /tmp/newrelic

  • Edit the scripts/devel.sh, Add the javaagent flags

    java -server -Xmx1024m -Dstage=development -Dnewrelic.config.file=/tmp/newrelic/newrelic.yml -javaagent:/tmp/newrelic/newrelic.jar -jar “$ROOT_DIR”/kestrel_2.9.2-2.4.1.jar 4. Run scripts/devel.sh and you will see the above error.

Any idea? Actually I have fire a ticket to NewRelic but got no answer from them for a whole month, I hope the community and @lewis-cirne (NewRelic CEO) can shield some light on this
