A very simple way is defining your custom message in exception handler (@ControllerAdvice), as following:

@ResponseStatus(HttpStatus.UNAUTHORIZED)
@ResponseBody
@ExceptionHandler(value = AuthenticationException.class)
public ResponseModal handleAuthenticationExceptions(AuthenticationException ex, HttpServletResponse response) {
    LOGGER.info("Authentication Exception: {}", ex.getMessage());
    response.addCookie(new Cookie(JWTConfigurer.JWT_TOKEN_COOKIE, null));
    return new ResponseModal(HttpStatus.UNAUTHORIZED.value(), "whatever you want");
}
