title: Which jdk used by spring-boot maven plug-in?
body: <p>I build all my java projects with the command :</p>
  <pre><code>mvn spring-boot:run 
  </code></pre>
  <p>I'd like to know which jdk (and how) is used :</p>
  <ul>
  <li>to build java project</li>
  <li>to run java project</li>
  </ul>
  <p>by spring-boot maven plugin ?</p>
  <p>In fact, it seems that the jdk should not be the same for the build and the run.</p>
  <p>How does it work ?</p>
