SpringBoot Spring Boot 3 AOT and scope proxies

Hi,

Given the following pom.xml:

            </plugin>
        </plugins>
    </build>
</project>

and given the following code:

package com.example.scopes;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Lazy;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Component;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.context.WebApplicationContext;

import java.util.UUID;

@SpringBootApplication
public class ScopesApplication {

    public static void main(String[] args) {
        SpringApplication.run(ScopesApplication.class, args);
    }
}

@Component
@Scope(WebApplicationContext.SCOPE_REQUEST)
class RequestContext {

    private final String uuid = UUID.randomUUID().toString();

    public String getUuid() {
        return uuid;
    }
}

@RestController
class ContextHttpController {

    private final RequestContext context;

    @Lazy
    ContextHttpController(RequestContext context) {
        this.context = context;
    }

    @GetMapping("/get")
    String uuid() {
        return this.context.getUuid();
    }
}

assuming i compile it with

mvn -DskipTests -Pnative native:compile

i get the following error:

for what it's worth, this used to work in earlier snapshots, from around September.

Proxies are a Spring Framework feature so there's nothing we can do in Spring Boot. There are a few existing issues in Framework's tracker about AOT and proxies. Please review those and open a new Framework issue if none of the existing issues covers your problem.
