public class PrivilegedActionException

extends Exception

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.
