The following is a good replacement for fibry for now:

import com.sun.net.httpserver.HttpServer 
import java.net.InetSocketAddress

...

        val server = HttpServer.create(new InetSocketAddress(port), 32)                                                                                                  

        server.createContext("/", ex => {
            val response = "Hi there!";                                                                                                                                  
            val bytes = response.getBytes()
            try {
              ex.sendResponseHeaders(200, bytes.length);//response code and length
              val os = ex.getResponseBody();
              os.write(bytes);
              os.close();                                                                                                                                                
            } catch {                                                                                                                                                    
              case e: Exception =>
                println("exception: " + e)
            }
        });
        server.start()
