title: SonarQube Stopped with Error
body: <p>I am new to SonarQube. I installed it to analyze my code on jenkins. When I edited properties file and run start command, the process stopped shortly after I started it. I went to web.log file and got this message:</p>
  
  <pre><code>[o.s.s.p.Platform] Web server startup failed: Current version is too old. Please upgrade to Long Term Support version firstly.
  </code></pre>
  
  <p>I have java-8, mysql 14.14 and SonarQube 6.5.</p>
  
  <p>What is it actually complaining? What is too old?</p>
