title: Stop output from drools when starting OptaPlanner from a JAR
body: <p>How to stop the drools logger when executing OptaPlanner from a compiled JAR?</p>
  
  <p>In the logback.xml file the drools output is commented out and when i run the project directly from Eclipse everything is ok the only output is the one from OptaPlanner (either debug or trace) , but when i compile everything into a JAR and run it from the JAR for some reason i also get the drools output.</p>
