Nullpointer exception on toJson();

[GoogleCodeExporter]

What steps will reproduce the problem?
package com.thundashop.app.banner;

import com.google.gson.Gson;
import com.google.gson.GsonBuilder;

public class ATest {
    class Test {
        String test = "test";
        Class something = null;
    }

    private void run() {
        Test test = new Test();
        System.out.println(test.test);

        Gson gson = new GsonBuilder().serializeNulls().create();
        String json = gson.toJson(test);
        System.out.println(json);
    }

    public static void main(String[] args) {
        ATest test = new ATest();
        test.run();
    }
}

What is the expected output? What do you see instead?
I have no idea. a string?
Fails due to Class something = null;

What version of the product are you using? On what operating system?
gson 2.2, linux ubuntu 12.04

Please provide any additional information below.
