scala gson array parsing

Please explain whats wrong with the code, I'm getting the output as {} empty. How should I get the json output.

val values = (1 to 10).toList
 val topic = "linkedlists"
 val gson = new GsonBuilder().create()
 val output=gson.toJson(values,classOf[List[Int]])
 println(output)

because java.

you can use java.util.List not scala.collection.immutable.List

example, 

import scala.collection.JavaConverters._
val list = (1 to 10).asJava

val gson = new GsonBuilder().create()
gson.toJson(list, classOf[java.util.List[Int]]) shouldBe "[1,2,3,4,5,6,7,8,9,10]"
