gson does not convert map of JSONObject correctly

[GoogleCodeExporter]

What steps will reproduce the problem?
1. create map<String,Object> where String is key and Object is valid JSONObject
2. gson.toJson(map)
3. produces extra 'map' structures

What is the expected output? What do you see instead?

{
    "data": {
            "sender": {
                    "id": "blah",
                    "preferences": {
                    }
                }
            },
            "recipients": {
                    "userid": "2",
                    "type": "GUEST"
                }
            }
        }
    }
}

but getting

{
    "data": {
        "map": {
            "sender": {
                "map": {
                    "id": "blah",
                    "preferences": {
                        "map": {}
                    }
                }
            },
            "recipients": {
                "map": {
                    "userid": "2",
                    "type": "GUEST"
                }
            }
        }
    }
}

while searching, i found out that it is due to how JSONObject is implemented. 
but having 'map' as wrapper when converted to json does not seem to make sense. 
please reconsider.
