+ * This exception is thrown by
+ * <code>doPrivileged(PrivilegedExceptionAction)</code> and
+ * <code>doPrivileged(PrivilegedExceptionAction,
+ * AccessControlContext context)</code> to indicate
+ * that the action being performed threw a checked exception.  The exception
+ * thrown by the action can be obtained by calling the
+ * <code>getException</code> method.  In effect, an
+ * <code>PrivilegedActionException</code> is a "wrapper"
+ * for an exception thrown by a privileged action.
+ *
+ * <p>As of release 1.4, this exception has been retrofitted to conform to
+ * 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."
