    I don't think this is correct for nested object structures. Suppose we have the following class structure:
    
    ```java
    public class Person {
       private String name;
       private Address address;
    }
    
    public class Address {
       private String city;
       private String zip;
    }
    ```
    
    Translating this to JavaScript/JSON should look like this if both, Person and Address use the JsonToStringStyle for their equals method:
    
    ```JavaScript
    {
       "name": "Peter",
       "address": {
          "city": "New York",
          "zip": "10026"
       }
    }
    ```
    
    If we apply this fix, the result will look like this:
    
    ```JavaScript
    {
       "name": "Peter",
       "address": "{
          "city": "New York",
          "zip": "10026"
       }"
    }
    ```
    
    Note the additional double quotes around the address object.
