HTTP Service Interface Client doesn't work for Native Image

[imaxvell]

It appears that new http service clients are not getting proper configuration from application.properties, as a result these clients don't work at all. This happening when running Spring Boot application in Native Image mode.

For example:
we have following application.properties

spring:
  http:
    clients:
      connect-timeout: 5000
      read-timeout: 5000
    serviceclient:
      myclient:
        base-url: https://example.com

And following config for this client:

@Configuration
@ImportHttpServices(group = "myclient", types = MyClient.class)
public class RestClientsConfig {
}

Where MyClient.java is

public interface MyClient {

    @GetExchange("/hello")
    SomeResponseDto hello();
}

Now when we try to call our client myClient.hello() we'll get

This exception

I'm using Spring Boot 4.0.3 and gradle plugin org.graalvm.buildtools.native 0.11.4. Image is built by ./gradlew bootBuildImage

There is no issue when running application in standard(non-native) mode

Could you please provide a complete minimal sample (something that we can unzip or git clone, build, and deploy) that reproduces the problem.
