我面临一个奇怪的问题，我对 Android 和 Json 很陌生。我正在使用一个 RESTful WCF，它显示一个像这样的 json 响应：

我正在尝试使用 Jackson 1.9.11 将其反序列化为复杂对象。
所以我用
final ObjectMapper mapper = new ObjectMapper();
RawResult<RawCatalogs> oResult = mapper.readValue(strResponse, new TypeReference<RawResult<RawCatalogs>>() {});
RawResult 是一个带有模板的类，而 RawCatalogs 是一个带有嵌套对象的类，它曾经正确地反序列化响应，但现在它在标题中显示错误。
类的定义是这样的（不知道嵌套类的信息是否需要完全支持？我想我已经很好地映射了它们，只是为了清楚起见将重要的发布）

所以我的问题是为什么它显示该错误？我在 stackoverflow 上搜索了类似的问题，似乎都是关于编码错误但不是相同的代码错误，而且我无法控制 WCF。
实际上，如果我在此页面中复制粘贴 Json 响应，它似乎格式正确。
我也尝试使用 mapper.configure 但 Jsonparser 的所有功能都不起作用
我究竟做错了什么？
