Gson List<HashMap<String,HashMap<String,String>>>

Существует JSON

Каким образом это спарсить в

List<HashMap<String,HashMap<String,String>>>

Хочу получить нечто похожее вль на такую структуру на примере декодирования этого JSON в php

Пробовал вот такой вариант

String Sessions //JSON
Type listType = new TypeToken<List<HashMap<String,HashMap<String,String>>>>() {}.getType();
ArrayList<HashMap<String,HashMap<String,String>>> SessionsList = new Gson().fromJson(Sessions, listType)

К сожалению не работает
