How to iterate over a Jackon JsonNode / Java Map Entry iterator in Scala

gistfile1.txt

import scala.collection.JavaConverters._
import com.fasterxml.jackson.core.JsonFactory
import com.fasterxml.jackson.databind.JsonNode
import com.fasterxml.jackson.databind.node.{JsonNodeFactory, MissingNode, ObjectNode}

val jf = new JsonFactory(true)
val o = new ObjectNode(jf)
o.put("yellow","banana")

for (v <- o.fields.asScala) { println(v.getKey(),v.getValue()) }
// (yellow,"banana")

Also asScala creates a Scala-like collection which can be chained with .foreach, .map, etc.
