As far as I see, you have created a circular dependency where the class depends on the instance of the completely same class which generally doesn't make sense at all 🙁

Yup, it doesn't make any sense - but any log would be helpful :)
I've added comment to my gist about this.

I think - if it's not much work - printing error that circular dependency occurs will be always helpful
