  /**
   * Consider this example.
   *
   * <p>Your application code contains a helper method that calls
   *
   * <pre>
   * Class.forName(classNameString).
   *
   * That method is called from a plugin class.
   *
   * The classNameString specifies a class that is contained in the plugin
   * JAR.
   * </pre>
   *
   * <p>The author of the plugin has the reasonable expectation that the class should be loaded.
   * However, the helper method's class was loaded by the system class loader, and that is the class
   * loader used by Class.forName. The classes in the plugin JAR are not visible. This phenomenon is
   * called classloader inversion.
   *
   * <p>To overcome this problem, the helper method needs to use the correct class loader. It can
   * require the class loader as a parameter. Alternatively, it can require that the correct class
   * loader is set as the context class loader of the current thread.
   *
   * <p>Each thread has a reference to a class loader, called the context class loader. The main
   * thread's context class loader is the system class loader. When a new thread is created, its
   * context class loader is set to the creating thread's context class loader. Thus, if you don't
   * do anything, then all threads have their context class loader set to the system class loader.
   *
   * <p>The helper method can then retrieve the context class loader:
   *
   * <pre>
   * Thread t = Thread.currentThread();
   * ClassLoader loader = t.getContextClassLoader();
   * Class cl = loader.loadClass(className);
   * </pre>
   *
   * <p>It might surprise you, however, that you can have two classes in the same virtual machine
   * that have the same class and package name. A class is determined by its full name and the class
   * loader. This technique is useful for loading code from multiple sources. For example, a browser
   * uses separate instances of the applet class loader class for each web page. This allows the
   * virtual machine to separate classes from different web pages, no matter what they are named.
   *
   * <p>Because each applet is loaded by a separate class loader, these classes are entirely
   * distinct and do not conflict with each other.
