Example for customising AuthenticationEventPublisher does not work

Describe the bug
https://docs.spring.io/spring-security/reference/6.4/servlet/authentication/events.html has the following example:

DefaultAuthenticationEventPublisher authenticationEventPublisher =
        new DefaultAuthenticationEventPublisher(applicationEventPublisher);
authenticationEventPublisher.setDefaultAuthenticationFailureEvent
        (AbstractAuthenticationFailureEvent.class);

This does not work, as AbstractAuthenticationFailureEvent is abstract, and attempting to call its constructor throws an InstantiationException, which is silently ignored.

To Reproduce
Follow the directions given in the documentation.

Expected behavior
All authentication exceptions are resolved to a failure event, even if not individually registered.

Start with the authentication events documentation page and the DefaultAuthenticationEventPublisher example described in the issue. Check how the default authentication failure event is instantiated and how AbstractAuthenticationFailureEvent is handled. Done means the documented example works and unregistered authentication exceptions resolve to a failure event without an instantiation failure.
