* value of the error code of the exception; e.g.
* throw new PKCS11Exception(PKCS11Constants.CKR_CANCEL);
*
* causes a return value of CKR_CANCEL.
*
* @param session
* The session performing the callback.
* @param surrender
* See CK_NOTIFICATION in PKCS#11. A return value of CKR_OK is
* generated, if this method call returns regularly.
* CKR_CANCEL can be returned to the module by throwing a
* PKCS11Exception with the error-code CKR_CANCEL.
* @param application
* The application-object passed to openSession.
* @exception PKCS11Exception
* If the method fails for some reason, or as PKCS11Exception
* with error-code CKR_CANCEL to signal the module to cancel
* the ongoing operation.
