title: Can't run STS after change to Java 7 version
body: <p>I was following this instruction and set my STS environment to use Java 7, instead of Java 8 <a href="https://stackoverflow.com/questions/32416540/http-status-500-servlet-init-for-servlet-fittrackerservlet-threw-exception">HTTP Status 500 - Servlet.init() for servlet fitTrackerServlet threw exception</a> </p>
  
  <p>And now when I want to run STS, I get this error message:</p>
