| 29 | * This exception is thrown by | ||
| 30 | * <code>doPrivileged(PrivilegedExceptionAction)</code> and | ||
| 31 | * <code>doPrivileged(PrivilegedExceptionAction, | ||
| 32 | * AccessControlContext context)</code> to indicate | ||
| 33 | * that the action being performed threw a checked exception. The exception | ||
| 34 | * thrown by the action can be obtained by calling the | ||
| 35 | * <code>getException</code> method. In effect, an | ||
| 36 | * <code>PrivilegedActionException</code> is a "wrapper" | ||
| 37 | * for an exception thrown by a privileged action. | ||
| 38 | * | ||
| 39 | * <p>As of release 1.4, this exception has been retrofitted to conform to | ||
| 40 | * the general purpose exception-chaining mechanism. The "exception thrown | ||
| 41 | * by the privileged computation" that is provided at construction time and | ||
| 42 | * accessed via the {@link #getException()} method is now known as the | ||
| 43 | * <i>cause</i>, and may be accessed via the {@link Throwable#getCause()} | ||
| 44 | * method, as well as the aforementioned "legacy method." | ||
