      classLoaderOrder - a ClassLoaderOrder object to update.
      log - the log

    • getPaths

      private static Collection<Object> getPaths(Object containerClassLoader, ReflectionUtils reflectionUtils)
      Get the paths from a containerClassLoader object.

      The passed in object should be an instance of "com.ibm.ws.classloading.internal.ContainerClassLoader".
