Free throw violation or not?

[Philz]

Once in awhile I see a player outside the 3 point line / free throw line extended on a free throw take a running start towards the basket but dont actually brake the plane before for it hits the rim (NHFS) or on the release(NCAA) but always see it called as a violation. I've even called it myself...nobody seems to question it but in the rule book I only seen it stated as they can not break the plane....can anyone help me out on that one?
