Missing tag "context" in action.devices.EXECUTE intent

[alexriva]

I have got from Google this payload:

{
    "inputs": [
        {
            "context": {
                "locale_country": "US",
                "locale_language": "en"
            },
            "intent": "action.devices.EXECUTE",
            "payload": {
                "commands": [
                    {
                        "devices": [
                            {
                                "id": "9MX4sq"
                            }
                        ],
                        "execution": [
                            {
                                "command": "action.devices.commands.OnOff",
                                "params": {
                                    "on": true
                                }
                            }
                        ]
                    }
                ]
            }
        }
    ],
    "requestId": "10539151787583144316"
}

When I try to unmarshall with generated java class from json schema I have got the error:

org.codehaus.jackson.map.exc.UnrecognizedPropertyException: Unrecognized field "context" (Class com.google.actions.api.smarthome.intents.execute.Input), not marked as ignorable
