title: Sonar JIRA Plugin: "Link to JIRA" is missing
body: <p>After installing the <a href="http://docs.codehaus.org/display/SONAR/Jira+Plugin" rel="nofollow">Sonar JIRA plugin</a> and restarting the Sonar server, I have run an analysis with the following properties configured in the Sonar Ant task:</p>
  
  <ul>
  <li>sonar.jira.url (no HTTPS used) </li>
  <li>sonar.jira.login.secured</li>
  <li>sonar.jira.password.secured </li>
  <li>sonar.jira.url.param (a JIRA filter)</li>
  <li>sonar.jira.project.key (the project key that is also used as prefix in JIRA issue keys)</li>
  </ul>
  
  <p>The JIRA widget shows results for the configured JIRA filter, but the item "Link to JIRA" is missing from the "More actions" pop-up menu. I have tried this with Sonar 3.0, 3.4.1 and 3.5.</p>
  
  <p>What could be wrong?</p>
