we (me and my friend) found an xray bug

Jaca_ (me) and Hirodbr (my friend) founded an xray bug involving pistons redstone and some ender pearls, one of my friends told me that we could get the "mojira moderator cape" for reporting a bug, soo here we are. You don't take damage when you are doing the bug (only the ender pearl damage or if you do it wrong)
