title: Jenkins - add JDK 11 to JDK list
body: <p>I need to build my application using Java 11.<br>
  However the dropdown menu stops at Java 9.</p>
  
  <p>What do I do? OpenJDK is acceptable too.<br>
  I'm on the latest version of Jenkins.</p>
  
  <p>Edit: as of now I've downloaded the binaries using <code>wget</code>, extracted them on the machine, and added a JDK <code>JDK_HOME</code> entry via Global Configurations.</p>
