Having this simple RESTeasy RxJava2 service:

    
    @GET    @Produces(MediaType.APPLICATION_JSON)
    @Stream    public Flowable<String> getTimeZoneStream()
    {
      return Flowable.create(flowableEmitter ->
      {
        locations.forEach(location -> flowableEmitter.onNext(location));
        flowableEmitter.onComplete();
      }, BackpressureStrategy.BUFFER);
    }
 
I'm getting the following exception:
 
    024-09-03T14:55:16+02:00 WARN  [org.jboss.resteasy.resteasy_jaxrs.i18n] (main) RESTEASY002155:  Provider class org.jboss.resteasy.rxjava2.FlowableRxInvokerProvider is already registered.  2nd registration is being ignored.

when trying to call it with the following client:
 
    ...
    try (Client client = ClientBuilder.newClient().register(FlowableRxInvokerProvider.class))
    {
      FlowableRxInvoker invoker = client.target(timeUri).request().rx(FlowableRxInvoker.class);
      Flowable<String> flowable = (Flowable<String>) invoker.get();
      ...
    }
    ...
 
I'm using the following dependencies:
 
        ...
    <dependency>
      <groupId>org.jboss.resteasy</groupId>
      <artifactId>resteasy-client</artifactId>
      <scope>provided</scope>

What might be the problem here ?
