| 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." | |
