No, I think they saw the pics in this topic and the damage was probably obvious enough for them to send out a new bar.
That's the usual worry we have overhere when it comes to warranty issues; having to send stuff back again overseas with the shippingcosts making it uninteresting to persue the warranty.

I think JS did a nice job in dealing with this.

The hex ends are not milled or machined at all, they are forged.
I had another close look at the broken hex end the other day and noticed the crack runs up upto the end of the bar.
