Facebook Messenger bot object structure for java

Has anyone created an open source project that provides the facebook messenger bot API in java? (or another language that I could convert?)

Essentially a hierarchy of objects for the stack, found at: https://developers.facebook.com/docs/messenger-platform/send-api-reference

I would rather not just use JsonObjects, etc., nor Maps to extract incoming JSON chat messages or to create outgoing structured chat responses. If there is an open source project for this, I have not found it.

FaceBot. FaceBot - Facebook Messenger: FaceBot 5 , -.

:

public class MyFaceBotBehavior extends AbstractFaceBot {

  public void defineBehavior() {
     // Setting my tokens from Facebook (page token and validation token for webhook).
     FaceBotContext.getInstance().setup("myFacebookPageToken", "myFacebookWebhookValidationToken");

     // Defining a bot which will reply with "Hello World!" as soon as I write "Hi"
     addActionFrame(new MessageEvent("Hi"),
          new MessageAutoReply("Hello World!"));
 }
}
