Description

I'm writing a Spring Security configurer and trying to add it to my configuration using apply(C), but the Groovy compiler selects the wrong overload, and necessary initialization is not performed.

@Grab('org.springframework.security:spring-security-config:5.7.11')
import org.springframework.security.config.annotation.authentication.builders.*
import org.springframework.security.config.annotation.web.configurers.*
import org.springframework.security.config.annotation.web.builders.*
@Grab('org.springframework.security:spring-security-web:5.7.11')
import org.springframework.security.web.*
@Grab('javax.servlet:servlet-api:2.5')
// AbstractHttpConfigurer extends SecurityConfigurerAdapter
class MyConfigurer extends AbstractHttpConfigurer<MyConfigurer, HttpSecurity> {}

SecurityFilterChain securityFilterChain(HttpSecurity http) {
  http.apply(new MyConfigurer())
     // ^ should select apply(SecurityConfigurerAdapter), but selects apply(SecurityConfigurer)
    .and()
    .build()
}

securityFilterChain(new HttpSecurity({ }, new AuthenticationManagerBuilder({ }), [:]))

This is probably a result of an edge case in the generics, since the bounds on the overloads are determined by type parameters.
