Eric Milles updated GROOVY-11204:
---------------------------------
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.
{code:groovy}
@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> {}
// configuration
@Bean
SecurityFilterChain securityFilterChain(HttpSecurity http) {
http.apply(new MyConfigurer())
// ^ should select apply(SecurityConfigurerAdapter), but selects
apply(SecurityConfigurer)
.and()
.build()
}
{code}
This is probably a result of an edge case in the generics, since the bounds on
the overloads are determined by type parameters.
