title: Jenkins is not starting the build upon SQS message arrival
body: <p><em>Tools:</em></p>
  
  <ul>
  <li>Jenkins version 1.506</li>
  <li>GitHub</li>
  <li>GitHub SQS Plugin 1.4</li>
  </ul>
  
  <p>Jenkins configured to consume the messages and GitHub for sending them over Amazon SQS (set the active key and secret key and queue name).  Also configured for modules with "Build when a message is published to an SQS Queue"
  The messages are sent by GitHub and consumed by Jenkins as warranted. I can see SQS Activity in Jenkins (see below) but for some reason Jenkins does not trigger the build.  </p>
  
  <p>I wonder what are we missing?</p>
  
  <p>Last SQS Activity</p>
