It was sad to learn that you must write custom serialization for the simple goal of wrapping a class with a labeled object. After playing around with writing a custom serializer, I concluded that the simplest solution is a generic wrapper. Here's perhaps a more simple implementation of your example above:

public final class JsonObjectWrapper {
    private JsonObjectWrapper() {}

    public static  Map withLabel(String label, E wrappedObject) {
        HashMap map = new HashMap();
        map.put(label, wrappedObject);
        return map;
    }
}
