So, as far as I stepped through with netbeans the json parser returns a list, wich is a json object, but requires a json array. Does this mean that the google oauth lib is not compatible with twitch - or that twich sends a reply not conform to oauth rfc (have to check this one next)?
//small edit
Stepped through again, and when the parser comes to the array it says the type is just a String instead of an array. I don’t know if there’s an error in the parser or the json replied by twitch is not valid json.
