As of release 1.4, this exception has been retrofitted to conform to
the general purpose exception-chaining mechanism. The "optional exception
that was raised while loading the class" that may be provided at
construction time and accessed via the
getException() method is
now known as the cause, and may be accessed via the
Throwable.getCause() method, as well as the aforementioned "legacy method."
