Does anyone have an idea why would this code cause dependency cycle?

```
@Configuration
@EnableWebSecurity
class WebSecurityConfig(private val authenticationManager: AuthenticationManager) : WebSecurityConfigurerAdapter() {
    // empty
}
```

```
┌─────┐
|  webSecurityConfig defined in file [C:\Users\...\WebSecurityConfig.class]
↑     ↓
|  authenticationManager defined in class path resource [org/springframework/boot/autoconfigure/security/AuthenticationManagerConfiguration.class]
└─────┘
```

why do you need to inject `AuthenticationManager` into `WebSecurityConfig`?
