Paul, Something is calling JSONParser with a parameter that's causing the stack overflow.
You can use Firebug to see what the browser is sending to the server. That's a way to capture the JSON. Wireshark is a way of intercepting the HTTP traffic and you can see what the client is sending to the server. If you can provide me with the String that's causing the JSON parsing failure, I can add it to the test suite and fix the bug.
