ArrayList's get(), set(), and add() methods were not inlinable, and this could be

has been 5x slower than it needed to be.  They never fixed this: it's still 

broken.  But the Hotspot crew has special-cased it internally to compensate.

Nope. Yeah, I know what that's like. Shortly after DOS Microsoft took control 

of all hardware and software vectors. Fair enough in a sense, but they provided 

no mechanism for high speed access. At first they wouldn't even give us a 

hook. It messed up our nicely performing frame animation code. By the time 

they provided high performance hooks I wasn't developing software animation 

any more.
