/**
* This exception is thrown by
* doPrivileged(PrivilegedExceptionAction) and
* doPrivileged(PrivilegedExceptionAction,
* AccessControlContext context) to indicate
* that the action being performed threw a checked exception. The exception
* thrown by the action can be obtained by calling the
* getException method. In effect, an
* PrivilegedActionException is a "wrapper"
* for an exception thrown by a privileged action.
*
* 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
* cause, and may be accessed via the {@link Throwable#getCause()}
* method, as well as the aforementioned "legacy method."
