title: How to disable loggers from class or a package which is from external jar
body: <p>External jar <strong><em>selenium-server-2.42.2</em></strong> is included to my java project.
  I want to disable the logging from some of the classes of this external jar
  I added below line in <strong><em>log4j.properties</em></strong> file </p>
  
  <pre><code>log4j.logger.org.openqa.selenium.remote.RemoteWebDriver=OFF
  </code></pre>
  
  <p>But still logs are displayed on a console as below</p>
  
  <blockquote>
    <p>13:08:36.283 INFO - Executing: [find elements: By.xpath:
    //div[contains(@class,'loading-spinner')]])</p>
