 * {@code PrivilegedActionException} is a "wrapper"
 * for an exception thrown by a privileged action.

 * the general purpose exception-chaining mechanism. The "exception thrown
 * by the privileged computation" that is provided at construction time and
 * accessed via the {@link #getException()} method is now known as the
 * <i>cause</i>, and may be accessed via the {@link Throwable#getCause()}
 * method, as well as the aforementioned "legacy method."
