title: /tmp/tomcat-docbase is always created with a Spring Boot JAR (but not a WAR)
body: <p>From STS I'm creating a standard Spring Boot 1.5.2 'Web' project.  If you run this application you get two directories created - the normal 'base' directory and a 'tomcat-docbase' directory</p>
  <pre><code>. . .  4096 Mar 29 10:00 tomcat.2743776473678691880.8080
  . . .  4096 Mar 29 10:00 tomcat-docbase.76291847886629412.8080
  </code></pre>
  <p>If I change this project to a WAR project I get only the 'base' directory</p>
  <pre><code>. . .   4096 Mar 29 10:06 tomcat.3131223012454570991.8080
  </code></pre>
  <p>It's easy to override the default base directory using</p>
  <pre><code> server.tomcat.basedir=.
  </code></pre>
  <p>however this has no effect on tomcat-docbase.  It is possible to override tomcat-docbase programmatically but seems like a hack.</p>
  <p>Does anyone think this is a bug?</p>
