Spawn multiple JVMs when running the remoting tests, to simulate more real-world scenarios.
Use something like below:

  def spawnJVM(clazz: Class[_ <: AnyRef], arg: Option[String]): Process = {
    val Xms        = "-Xms256m"
    val Xmx        = "-Xmx512m"
    val separator  = System.getProperty("file.separator")
    val classpath  = System.getProperty("java.class.path")
    val pathToJava = System.getProperty("java.home") + separator + "bin" + separator + "java"
    if (arg.isEmpty) (new ProcessBuilder(pathToJava, Xms, Xmx, "-cp", classpath, clazz.getCanonicalName)).start
    else             (new ProcessBuilder(pathToJava, Xms, Xmx, "-cp", classpath, clazz.getCanonicalName, arg.get)).start
  }
