    Description

      Java 9+ changed how ClassLoaders work. The two most salient points:

      The boot classloader no longer 'sees' the platform classes. A new 'platform classloader' does and should be the parent of new ClassLoaders
      The system classloader is no longer a URLClassLoader, so we can't get the URLs of JARs in its classpath
