Given the following sample: https://github.com/Eng-Fouad/spring-native-lazy-bug
I got an exception on running the native image:

Removing @Lazy in both cases, resolves the problem for me and the native image works normally.
Comment From: Eng-Fouad
I tried registering SampleService as reflection hint, but it didn't fix the problem:
MyRuntimeHints:
package io.fouad.lazynative;
import org.springframework.aot.hint.RuntimeHints;
import org.springframework.aot.hint.RuntimeHintsRegistrar;
public class MyRuntimeHints implements RuntimeHintsRegistrar {
@Override
public void registerHints(RuntimeHints hints, ClassLoader classLoader) {
hints.reflection().registerType(SampleService.class);
}
}
SpringLazyNativeApplication:
package io.fouad.lazynative;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ImportRuntimeHints;
@SpringBootApplication
@ImportRuntimeHints(MyRuntimeHints.class)
public class SpringLazyNativeApplication {
public static void main(String[] args) {
System.out.println("Hello World");
org.springframework.boot.SpringApplication.run(SpringLazyNativeApplication.class, args);
}
}

@Eng-Fouad thanks for the report and the sample but please move all that text into an actual sample that we can run. The only thing we could to help is to do that anyway and there's a chance in doing so that we miss one piece. An url to a GitHub repo is ideal or, alternatively, a ZIP attached to this issue.

As a workaround for the second exception:

registerClass(hints, SampleService.class);
}
private static <T> void registerClass(RuntimeHints hints, Class<T> clazz) {

try {
proxyClass = Class.forName("%s$$SpringCGLIB$$%d".formatted(clazz.getName(), i));

I just checked. It's working fine. Their is no exception while running the application. Is it fixed?

Did you run the native image?
Comment From: kamalkumar789
Assign me. I am working on that. Will give it you in an hour. Because I have checked it and solve it.

How did you solve this exception?
Caused by: java.lang.ClassCastException: org.springframework.aop.framework.CglibAopProxy$SerializableNoOp cannot be cast to org.springframework.cglib.proxy.Dispatcher
Comment From: Kareem-Afaneh
@Eng-Fouad Salam! Did you find a solution for the @Lazy issue? I get this exception as well..
Caused by: java.lang.ClassCastException: org.springframework.aop.framework.CglibAopProxy$SerializableNoOp cannot be cast to org.springframework.cglib.proxy.Dispatcher
Note i use Lazy for a self circular dependency.
Comment From: snicoll
You don't have to use @Lazy if you can change the method signature.Adding ObjectProvider for your type and removing the @Lazy annotation will have the same effect. Once you are ready to consume the depdendency you can call getObject on the ObjectProvider.
