I ran into a strange problem, I am very new to Android and Json. I am using RESTful WCF, which shows a json response similar to this:

I am trying to deserialize it to a complex object using Jackson 1.9.11.
Therefore i use
final ObjectMapper mapper = new ObjectMapper(); RawResult<RawCatalogs> oResult = mapper.readValue(strResponse, new TypeReference<RawResult<RawCatalogs>>() {});
Where RawResult is a class with a template and RawCatalogs, its class with nested objects, it was used to deserialize the response correctly, but now it shows an error in the header.
The definition of classes is (I don’t know if information about nested classes is needed for full support? I think I outlined them very well, just sending importers for clarity)

So my question is why is it showing this error? I was looking for similar questions about stackoverflow, everything seemed to be about a coding error, but this is not the same code error, nor do I control WCF.
In fact, if I copy the Json Respone paste into this page , it seems well formed.
I also tried using mapper.configure, but none of the Jsonparser functions worked
What am I doing wrong?
