Jerkson in Play2 development mode

Play2 includes Jerkson which is a Scala wrapper for the Java based JSON library Jackson.

It's very useful and I'm loving it. However when we use it in the Play2 application, it fails to deserialize case classes after reloading in development mode. See the following code:

import com.codahale.jerkson.Json

takezoe

val client = new SolrClient("http://localhost:8983/solr")

// search documents similar to the specified (id: 123456).
val result = client.query("id:123456")
  .fields("id, title, content")
  .recommend("title, content")
  .getResultAsMap()

result.documents.foreach {
  println("id: "      + doc("id"))
