/**
* 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.
