title: Something has installed Jetty and starts on boot-up
body: <p>After a macOS High Sierra (10.13.6) update, which required a reboot, I found that Jetty 9.4.z-SNAPSHOT was running on port 8080. </p>
  
  <p>As I use JBoss WildFly 13.0.0.Final I use Undertow as my web server and I have not intentionally installed Jetty. If I 'locate' Jetty it shows in the following directories (see quoted text at end). </p>
  
  <p>I did install Solr 6.x using brew and update it regularly. But it has never 'interfered' with JBoss WildFly before, even after reboots. </p>
  
  <p>I did not inadvertently install Jetty with Homebrew as:</p>
  
  <blockquote>
    <p>brew info jetty jetty: stable 9.4.11.v20180605 Java servlet engine and
    webserver <a href="https://www.eclipse.org/jetty/" rel="nofollow noreferrer">https://www.eclipse.org/jetty/</a> Not installed</p>
  </blockquote>
  
  <p>Can I just delete 'Jetty' and how can I see how/where Jetty is started from. Not shown in the macOS start-up? </p>
  
  <p>locate <em>/jetty</em></p>
