Spring boot reactive and GraalVM java.lang.NoClassDefFoundError: Could not initialize class reactor.netty.http.client.HttpClientSecure

Question

When I'm creating a native image using Spring reactive and WebClient everything ends correctly but when I'm making a request using the WebClient, I get this error given below :

2021-01-10 04:10:22.904 ERROR 1 --- [ctor-http-nio-2] reactor.netty.http.server.HttpServer     : [id: 0x3dd90c0b, L:/172.17.0.2:8080 - R:/172.17.0.1:48222]

This is my code

public Flux<User> getAllUser() {
        return webClient
                .get()
                .uri("/v1/07defb0d")
                .retrieve()
                .bodyToFlux(User.class);
    }

This is my full example code

Any suggestion for me?
