How can I use Gson in Scala to serialize a List?

Question

I was hoping to use Scala and Gson together. It seems to mostly work, but when I do something like this, it treats the list as an object, not an array:

case

You can use a java converter:

import scala.collection.JavaConverters._
case class MyType (val x:String, val y:List[SomeOtherType]) {
   def toJson() = new Gson().toJson(this.asJava())
}
