title: Why is sonarqube call from jenkins failing with HTTP 500?
body: <p>I have a build job running in jenkins analyzing a java code web project. The compilation and build part is working fine. The jobs fails when sonarqube is called.
  I get the following error message in jenkins:</p>

  <p>I am using <code>jenkins 1.646</code> with <code>oracle java 1.8.0_72-b15</code> running on <code>debian 7.9 (wheezy)</code>. SonarQube is version <code>5.3</code> with <code>PostgreSQL 9.1.18</code>. It uses the same java vm as they run on the same machine.</p>
  
  <p>There a jobs in this jenkins instance that do not fail and are able to submit there data to sonarqube, hence t he workflow is okay.</p>
  
  <p>I couldn't find anything useful to solve this problem via google and therefore need your help.</p>
  
  <p>Do you need any additional information?</p>
