  <p>this <code>Cucumber</code> <code>java</code> <code>junit</code> project with <code>Serenity</code>. Only difference between master and slave is that <code>Xvfb</code> (headless browser) is working on Master but not on Slave, but since it looks a Maven or Cucumber error I doubt <code>Xvfb</code> has anything to with it.</p>
  
  <p>What am I doing wrong?</p>
