Barb Mastery for Javelin Class?

[IronMouse]

I just found an ethereal Demon's Arch, which is a pretty nice weapon, even when not used as a throwing weapon. It's a javelin-class wpn, but Barb's don't have javelin mastery. Is it true that spear mastery applies to javelins when not thrown, and throwing wpn mastery applies when thrown?

Thanks,
