Hello,

I'm trying to run a simple service using Java 11, but i'm getting a runtime error..

My app just make a call to an external API using the java.net.HttpClient

@GET
@Path("/test")
@Produces("text/plain")
public Response getPokemons() throws IOException, InterruptedException {
    HttpClient httpClient = HttpClient.newBuilder().build();
    HttpRequest request = HttpRequest.newBuilder(URI.create("https://pokeapi.co/api/v2/pokemon/1")).build();
    HttpResponse<String> response = httpClient.send(request, BodyHandlers.ofString());
    return Response.ok(response.body()).build();
}

And this code throws a NoClassDefFoundError:

I already checked the generated jar, and the module java.base (with java.net.http inside) is there.
