Spring Load Time Weaving Not Working on @Configurable object

Question

Basically, what I want in the end, is that an object in some piece of code is wired up with my Spring Component, although that object is not created / managed by Spring.

The object in question is:

package demo;

import org.springframework.beans.factory.annotation.Autowire;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Configurable;

@Configurable(autowire= Autowire.BY_TYPE)
public class NotSoSpring {

  SpringComponent springComponent;

  public NotSoSpring() {
    springComponent.test();
  }

  @Autowired
  public void setSpringComponent(SpringComponent springComponent) {
    this.springComponent = springComponent;
  }

  public void test() {
    springComponent.test();
  }
}

And the component is as simple as that:

package demo;

import org.springframework.stereotype.Component;

@Component
public class SpringComponent {

  public void test() {
    System.out.println("Hello. Wow, this works!");
  }
}

The Spring configuration is done by the following piece of code:

package demo;

import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.EnableAspectJAutoProxy;
import org.springframework.context.annotation.EnableLoadTimeWeaving;
import org.springframework.context.annotation.aspectj.EnableSpringConfigured;

@SpringBootApplication
@EnableSpringConfigured
@EnableLoadTimeWeaving(aspectjWeaving = EnableLoadTimeWeaving.AspectJWeaving.ENABLED)
@EnableAspectJAutoProxy
@ComponentScan(basePackages = "demo")
public class DemoApplication implements CommandLineRunner {

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

  @Override
  public void run(String... strings) throws Exception {
    NotSoSpring spring = new NotSoSpring();
    spring.test();
  }
}

And here's the project's configuration:

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

That's all the files, and here's the JVM command line option I used:

-javaagent:c:/.m2/repository/org/springframework/spring-instrument/4.1.5.RELEASE/spring-instrument-4.1.5.RELEASE.jar

So this results in

I looked through other SO questions, the Spring Documentation and a lot of blogs, but unfortunately they usually refer to Spring 3 and to XML based configurations.

Might be related to this question which has no solution either.
