Class com.ecwid.consul.v1.kv.model.GetValue is instantiated reflectively but was never registered

Hi

We have Spring Boot application that uses Spring Cloud Config Consul. We added Spring Native plugin (for Gradle) and managed to build GraalVM native image however when we run the application we get the following exception:

Caused by: java.lang.IllegalArgumentException: Class com.ecwid.consul.v1.kv.model.GetValue is instantiated reflectively but was never registered. Register the class by using org.graalvm.nativeimage.hosted.RuntimeReflection
at com.oracle.svm.core.graal.snippets.SubstrateAllocationSnippets.hubErrorStub(SubstrateAllocationSnippets.java:258)
at sun.misc.Unsafe.allocateInstance(Unsafe.java:864)

JDK: 17.0.1
GraalVM: 21.3.0
Spring Boot: 2.6.2
Spring Native: 0.11.1
Spring Cloud: 2021.0.0

Can be resolved by this explicit configuration:

@Configuration
@TypeHint(types = GetValue.class, access = {TypeAccess.PUBLIC_CONSTRUCTORS, TypeAccess.PUBLIC_METHODS, TypeAccess.PUBLIC_FIELDS,
		TypeAccess.DECLARED_CONSTRUCTORS, TypeAccess.DECLARED_FIELDS, TypeAccess.DECLARED_METHODS})
public class AotConfig {
}

@OlgaMaciaszek Should we include that in Spring Cloud hints from your POV?

@sergey-morenets thanks for reporting this. Veryfying.

@sergey-morenets I've tried to reproduce this both against 0.10.6 and 0.11.2. However, I was not able to reproduce the issue. Instead, I've come across another issue related to using Spring Cloud Consul with native images. Please provide a minimal, complete, verifiable example that reproduces the issue - will look further into it then.

Closing due to lack of feedback.

@sergey-morenets, @sdeleuze after further analysis, I was able to reproduce this.

Will add the necessary hints.
