spring-cloud-starter-oauth2 and spring-boot-starter-webflux no server on start - spring-security-oauth2

Question

I have a simple spring application that use
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.0.BUILD-SNAPSHOT</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
My other dependencies are:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-oauth2</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-webflux</artifactId>
</dependency>
I'have created a dummy controller:
#RestController
public class Controller {
#GetMapping("/")
String get(){
return "HELLO";
}
}
When I start the app I have strange error:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'requestMappingHandlerMapping' defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/WebMvcAutoConfiguration$Enable WebMvcConfiguration.class]: Invocation of init method failed; nested exception is java.lang.ArrayStoreException: sun.reflect.annotation.TypeNotPresentExceptionProxy
It's seems that I have a conflict with spring-webmvc and webflux.
I want to be reactive and webmvc do not play well with spring reactive based on what I've read, So I've exclude spring-web-starter, but then I have...
org.springframework.context.ApplicationContextException: Unable to start reactive web server; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'httpHandler' defined in class path resource [org/springframework/boot/autoconfigure/web/reactive/HttpHandlerAutoConfiguration$AnnotationConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.http.server.reactive.HttpHandler]: Factory method 'httpHandler' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'webHandler' defined in class path resource [org/springframework/boot/autoconfigure/web/reactive/WebFluxAnnotationAutoConfiguration$EnableWebFluxConfiguration.class]: Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'requestMappingHandlerMapping' defined in class path resource [org/springframework/boot/autoconfigure/web/reactive/WebFluxAnnotationAutoConfiguration$EnableWebFluxConfiguration.class]: Invocation of init method failed; nested exception is java.lang.ArrayStoreException: sun.reflect.annotation.TypeNotPresentExceptionProxy
What is needed to make spring oauth2 works with spring-webflux ?
for info I am using snapshot for everything.
Thanks in advance

This is not supported at the moment (neither is the reactive bits of Spring Security).
