I am trying to convert some json to an object but am getting a XStream DuplicateFieldException. From googling, its suggested i should use "implicitCollections".

The JSON looks as follows:

{"emailRequest": {

  "to": [

    [

      "gareth@boohoo.com",

      "some@else.com"

    ]

  ],

  "email": {

    "subject": "ESB ALERT - activemq://Consumer.VendaUAT.VirtualTopic.sendStockToExternalServices",

    "message": "{\"inventoryChangedRequest\": {\u000a  \"inventory\": {\u000a    \"sku\": \"azz5876010433\",\u000a    \"quantity\": 42\u000a  }\u000a}}"

  }

}}

to is a List

This converts the collection to Objects, instead of Strings. Any idea how i'd get it to convert to a list of strings?
