title: Sonarqube 5.2 / Checkstyle plugin 2.3 : Enabling SummaryJavadocCheck makes the analysis failed
body: <p>I recently change my SONARQUBE configuration:</p>
  
  <p>Before:</p>
  
  <ul>
  <li>SonarQube 5.1  </li>
  <li>Java plugin 3.0</li>
  <li>PMD plugin 2.3</li>
  <li>Checkstyle plugin 2.2</li>
  <li>FindBugs plugin 3.2</li>
  <li>Issue Assign plugin 1.6</li>
  </ul>
  
  <p>After:</p>
  
  <ul>
  <li>SonarQube 5.1  </li>
  <li>Java plugin 3.3</li>
  <li>PMD plugin 2.4.1</li>
  <li>Checkstyle plugin 2.3</li>
  <li>FindBugs plugin 3.2</li>
  <li>Issue Assign plugin 1.6</li>
  </ul>
  
  <p>On new configuration I have enabled all new rules brought from 3.1 to 3.2 Java plugin version.  </p>

  <p>Any idea what happened?</p>
  
  <p><strong>EDIT:</strong></p>
  
  <p>I removed new rule <em>checkstyle:com.puppycrawl.tools.checkstyle.checks.javadoc.SummaryJavadocCheck</em> brought by checkstyle 2.3 plugin version. The analysis works correctly now.</p>
