title: Upgrading to Java 11 from Java 8 - package sun.util does not exist
body: <p>I'm trying to migrate an application from Java 8 to Java 11. When I try and build the project in IntelliJ I get a <code>package sun.util does not exist</code> error?</p>
  
  <p>Any ideas on what's up? </p>
  
  <p>Thanks!</p>
