Trying to parse String to Json and getting MalformedJsonException

[Guillermo Ortiz]

I'm try to parse a String to Json with GSON:

public static String navigate(final String path, String json){
   JsonParser parser = new JsonParser();
   JsonObject objJson = (JsonObject) parser.parse(json); //ERROR
   return navigate(path, objJson);
}

The JSON is well formatted and I don't have any error with the most of them. But, I get an error when I try to parse some of them.

If I try to reproduce the error with Junit, I don't get any error, so it's just when I package the code and execute it inside of Flume Agent.

I have checked all the JSON and they seem to have a "?", I don't know if it's the real reasson,,

Any clue about what's going on?
