Put "List of Objects" in KrollDict with Titanium Android Module Development

I have a custom class declared in the module source code.

public class Friend{
    public String name;
    public List<String> phoneNumbers;
    public List<String> emailAddresses;

    public Friend(String name, List<String>emailAddresses, 
    List<String>phoneNumbers){
        this.name = name;
        this.emailAddresses = emailAddresses;
        this.phoneNumbers = phoneNumbers;
    }
}

I declared an Android Method in the Module

@Kroll.method
protected synchronized void getListOfObjects(){
    List<String> emailAddresses = Arrays.asList("email1@yahoo.com", "email2@yahoo.com", "email3@yahoo.com");
    List<String> phoneNumbers = Arrays.asList("1", "2", "3");

    List<Friend> friendList = new ArrayList<Friend>();
    friendList.add(new Friend("test1", emailAddresses, phoneNumbers));
    friendList.add(new Friend("test2", emailAddresses, phoneNumbers));
    friendList.add(new Friend("test3", emailAddresses, phoneNumbers));


    KrollDict kd = new KrollDict();
    kd.put("friendList", friendList);
    if (hasListeners("onShow")) {
        fireEvent("onShow", kd);
    }
}

Upon Calling the getListOfOjects method in the Titanium App

module.getListOfObjects();
module.addEventListener('onShow', function(e){
    Ti.API.info(JSON.stringify(e.friendList));
});

I cant seem to retrieve the friendList object.

The EXPECTED RESULT that I wanted to achieve would be like this

[
    {test1, ["email1@yahoo.com", "email2@yahoo.com", "email3@yahoo.com"], ["1", "2", "3"]},
    {test2, ["email1@yahoo.com", "email2@yahoo.com", "email3@yahoo.com"], ["1", "2", "3"]},
    {test3, ["email1@yahoo.com", "email2@yahoo.com", "email3@yahoo.com"], ["1", "2", "3"]}
]

The question is, HOW TO ACHIEVE THE EXPECTED RESULT BASED ON THE SAMPLE CODES ABOVE?

Convert the List object into JSON string using GSON and assign the result string to the KrollDict property

KrollDict kd = new KrollDict();
Gson gson = new Gson();
String friendListStr = gson.toJson(friendList);
kd.put("friendList", friendListStr);
