docs: Loads the class defined with the given name and bytecode using the given
  class loader
  
  <p>Since package and class idendity includes the ClassLoader instance
  used to load a class, we use reflection on the given class loader to
  define generated classes.</p>
  
  <p>If we used our own class loader (in order to be able to access the
  protected "defineClass" method), we would likely still be able to load
  generated classes; however, they would not have access to package-private
  classes and members of their super classes.</p>
  
  @param className the full name of the class to be loaded
  @param bytecode the bytecode of the class to load
  @return the class instance
