akka dies with a java.lang.UnsatisfiedLinkError when run GraalVM native-image

I've been trying to very a (very) small native akka-http prototype with native-image from graalvm. The build is passing but there is an issue when running the resulting binary.

akka.util.Reflect contains the following code:

  val getCallerClass: Option[Int ⇒ Class[_]] = {
    try {
      val c = Class.forName("sun.reflect.Reflection")
      val m = c.getMethod("getCallerClass", Array(classOf[Int]): _*)
      Some((i: Int) ⇒ m.invoke(null, Array[AnyRef](i.asInstanceOf[java.lang.Integer]): _*).asInstanceOf[Class[_]])
    } catch {
      case NonFatal(e) ⇒ None
    }
  }

The selected method getCallerClass has been deprecated a while ago and is not suppoerted on Graalvm. This causes a java.lang.UnsatisifedLinkError, bubbling right up through the Try.

This is the resulting stacktrace:

This happens on:

akka: 2.5.12 scala: 2.12.5 akka-http: 10.1.1

I checked the current master and the code is also there.

This is the Main-method I used (please note that using App with Graalvm doesn't work currently because of this https://github.com/oracle/graal/issues/370 ):

object QuickstartServer {
  def main(args: Array[String]): Unit = {
    implicit val system: ActorSystem = ActorSystem("helloAkkaHttpServer")
    implicit val materializer: ActorMaterializer = ActorMaterializer()

    val routes: Route = pathPrefix("hello") {
      get {
        complete("World!")
      }
    }
    Http().bindAndHandle(routes, "localhost", 8080)

    println(s"Server online at http://localhost:8080/")

    Await.result(system.whenTerminated, Duration.Inf)
  }
}

And the contents of build.sbt:

lazy val akkaHttpVersion = "10.1.1"
lazy val akkaVersion    = "2.5.12"
retrieveManaged := true
lazy val root = (project in file(".")).
  settings(

      organization    := "de.codepitbull.graalvm",
      scalaVersion    := "2.12.5"
    )),
    name := "graalvm-akka-http",
    libraryDependencies ++= Seq(
