I've encountered weird behaviour of symfony that in my opinion is a bug:
I want to use SimpleForm authentication that was introduced in 2.4 and i want to set it with csrf token in login form, but when i add token an \InvalidArgumentException('Missing simple authenticator') is thrown. I've checked this and here is what i found.

SimpleFormAuthenticationListener has 12 parameters in constructor. Parameter 11th is token interface and 12th is simple form authenticator interface. When i set my csrf token to be disabled then in appDevDebugProjectContainer.php this 11th parameter is set to null and 12th parameter is my authenticator object. But when i enable crsf token in yml file by setting: csrf_provider: security.csrf.token_manager then in appDevDebugProjectContainer.php there is suddenly 13 parameters in listener constructor: 11th is token interface, 12th is set to null and 13th is my authenticator object. And that is why i get exception cause listener expects my authenticator to be on 12th position not 13th...

here is my security conf:
simple_form:
authenticator: webservice.security.authenticator
check_path: login_check
login_path: login
username_parameter: login[email]
password_parameter: login[password]
csrf_parameter: login[token]
intention: authenticate
remember_me: true
csrf_provider: security.csrf.token_manager

Maybe i do something wrong but i manage to make it work by creating my own listener with 13 parameters and pass constructor call to original one omitting this additional null parameter. When i run that, everything was ok.
