Updated Broken Scala Map to JSON to match recent package naming and language style

JacksonMapTest.scala

package test

import com.fasterxml.jackson.databind.ObjectMapper
import com.fasterxml.jackson.module.scala.DefaultScalaModule

object Main extends App {

  val mapper = new ObjectMapper()
  mapper.registerModule(DefaultScalaModule)

  val map = Map((2, 3) -> "Horsey")
  println(map)

  val out = mapper.writeValueAsString(map)
  println(out)

  val result = mapper.readValue(out, classOf[Map[Tuple2[Int, Int], String]])
  result.foreach(e => println(e._1.getClass))
}
