Nulls are getting treated as Strings

[jordanburke]

First of thanks for wrapping this for CN1. Been using it quite a bit and it's a pretty good lib.

I found an issue I didn't see until today. JSONObject ToString conversion causes nulls to be wrapped with double quotes causing them to treated as strings. I'll submit a patch if I get my env set up otherwise wanted to let you know.

Adding a Null object check like this or similar to the valueToString method:

        if (value instanceof Null) {
            return value.toString();
        }

Fixes the issue for me. Right now it falls to the end where it gets "quoted".

Thanks. Can you post a sample JSON string that fails, to demonstrate the problem?

Issue still active...

If you have a json object like:

{"key":null, "key2":"something"}

Reading it and calling the toString() method on the resulting JSONObject would produce this output:

{"key":"null", "key2":"something"}

So null is now wrapped with " and considered as a String value, wich is an issue.
