Unable create Custom Resource Definition with ApiextensionsV1Api.createCustomResourceDefinition()

[ardhendusaha]

Describe the bug
Hello,

I'm trying to create a custom resource following this official example:
https://github.com/kubernetes-client/java/blob/v24.0.0/kubernetes/docs/ApiextensionsV1Api.md#createCustomResourceDefinition

        V1CustomResourceDefinition result = apiInstance.createCustomResourceDefinition(body)
                .dryRun(dryRun)
                .execute();

No matter what I specify in the body , the result is always an HTTP 422 error response from the server:

   {"kind":"Status","apiVersion":"v1","metadata":{},"status":"Failure","message":"CustomResourceDefinition.apiextensions.k8s.io \"widgets.example.com\" is invalid: spec.validation.openAPIV3Schema.dependencies: Forbidden: dependencies is not supported","reason":"Invalid","details":{"name":"widgets.example.com","group":"apiextensions.k8s.io","kind":"CustomResourceDefinition","causes":[{"reason":"FieldValueForbidden","message":"Forbidden: dependencies is not supported","field":"spec.validation.openAPIV3Schema.dependencies"}]},"code":422}

Client Version
24.0.0

Kubernetes Version
v1.28.0

Java Version
Java 17

To Reproduce
Steps to reproduce the behavior:

Copy below java code and execute from local system.

       String kubeConfigPath = "C:\\Users\\Administrator\\WORK\\Projects\\java-client\\kube\\config";
        ApiClient client = Config.fromConfig(kubeConfigPath);
        Configuration.setDefaultApiClient(client);
        ApiextensionsV1Api apiInstance = new ApiextensionsV1Api(client);
        V1CustomResourceDefinition body = new V1CustomResourceDefinition();
        body.setApiVersion("apiextensions.k8s.io/v1");
        body.setKind("CustomResourceDefinition");
        body.setMetadata(new V1ObjectMeta().name("widgets.example.com"));
        List<V1CustomResourceDefinitionVersion> versions = new ArrayList<>();
        V1CustomResourceValidation schema = new V1CustomResourceValidation().openAPIV3Schema(new V1JSONSchemaProps().type("object").dependencies(new HashMap<>()));
        V1CustomResourceDefinitionVersion v1 = new V1CustomResourceDefinitionVersion().name("v1").served(true).storage(true).served(true).schema(schema);
        versions.add(v1);
        body.setSpec(new V1CustomResourceDefinitionSpec().group("example.com").names(new V1CustomResourceDefinitionNames().kind("Widget").plural("widgets")).scope("Namespaced")
                .versions(versions));
        body.setStatus(new V1CustomResourceDefinitionStatus().acceptedNames(new V1CustomResourceDefinitionNames().kind("Widget")));

        String dryRun = "All";
        V1CustomResourceDefinition result = apiInstance.createCustomResourceDefinition(body)
                .dryRun(dryRun)
                .execute();
