Builder method and inheritance about better-java HOT 3 CLOSED

I guess there would not be a clean solution, since as the Builder means, it builds a concrete class, nothing else, you just can not extends a builder and mix with it..

But anyway, here gives a approximately way to implement this(which also makes the code less readable)..

Hmm.. while the solution presented in that thread works, its hardly an elegant solution, thanks anyway!

It's a shame too, I thought that covariant types would allow me to make this work without any hassle.

Well it works, syntastic hates it and it looks like a hack, but it works.

Edit: On further notice, its not actually that bad, it looks a little weird for the superclass, but the inheriting classes seamlessly integrate it.
