Question

I am trying to make an exception subclass of AuthenticationException as follows:

public class RegistrationNotCompleteException extends AuthenticationException {
    public RegistrationNotCompleteException(String msg) {
        super(msg);
    }
}

and in the loadUserByUsername of my UserDetailsService class I make the following check:

if (!user.getHasRegistered()) {
    System.out.println("######## User: " + username
        + " has not completed the registration");
    throw new RegistrationNotCompleteException(
        "User has not completed registration");
}

so the user is forwarded to the AuthenticationFailureHandler class as expected.

But when trying to get the exception class in the onAuthenticationFailure method as follows:

public void onAuthenticationFailure(HttpServletRequest request,
    HttpServletResponse response, AuthenticationException exception)
    throws IOException, ServletException {

    UsernamePasswordAuthenticationToken token =
        (UsernamePasswordAuthenticationToken) exception.getAuthentication();
    String username = token.getName();
    String credentials = token.getCredentials().toString();
    System.out.println("Exception class: " + exception.getClass());

it prints that the exception class is AuthenticationException not RegistrationNotCompleteException.

And I want to verify that the exception class is RegistrationNotCompleteException.

Please advise how to do that.

solved by changing the check to exception.getCause().getClass() instead of exception.getClass()
