title: HTTPS failing after Sonar Upgrade
body: <p>I just completed the upgrade from SonarQube 5.3 to 5.6.  I copied my key/values from the prior <strong>sonar.properties</strong>.  Sonar is able to start up on HTTP but is generating errors when attempting to start up only with previously working HTTPS.</p>
  
  <p>My sonar.properties around HTTPS:</p>
  
  <pre><code>sonar.web.port=-1
  sonar.web.context=/sonar
  sonar.web.https.port=9000
  sonar.web.https.keyAlias=&lt;confirmed alias&gt;
  sonar.web.https.keyPass=&lt;confirmed password&gt;
  sonar.web.https.keystoreFile=&lt;confirmed file&gt;
  sonar.web.https.keystoreType=JKS
  </code></pre>
  
  <p>The error generated with the above config:</p>
  
  <pre><code>2016.06.10 02:05:46 INFO  web[o.s.p.ProcessEntryPoint] Starting web
  2016.06.10 02:05:46 WARN  web[o.s.p.ProcessEntryPoint] Fail to start web

  </code></pre>
  
  <p>As a test, I switched back to just HTTP:</p>
  
  <pre><code>sonar.web.port=9000
  sonar.web.context=/sonar
  #sonar.web.https.port=9000
  sonar.web.https.keyAlias=&lt;confirmed alias&gt;
  sonar.web.https.keyPass=&lt;confirmed password&gt;
  sonar.web.https.keystoreFile=&lt;confirmed file&gt;
  sonar.web.https.keystoreType=JKS
  </code></pre>
  
  <p>The info from that log:</p>

  <p>What am I missing that is causing HTTPS to not work?</p>
