/**
 * 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." * * @see PrivilegedExceptionAction * @see AccessController#doPrivileged(PrivilegedExceptionAction) * @see AccessController#doPrivileged(PrivilegedExceptionAction,AccessControlContext) */ public class PrivilegedActionException extends Exception { // use serialVersionUID from JDK 1.2.2 for interoperability private static final long serialVersionUID = 4724086851538908602L; /** * @serial */ private Exception exception; /** * Constructs a new PrivilegedActionException "wrapping" * the specific Exception. * * @param exception The exception thrown */ public PrivilegedActionException(Exception exception) { super((Throwable)null); // Disallow initCause this.exception = exception; } /** * Returns the exception thrown by the privileged computation that * resulted in this PrivilegedActionException. * *
