Did I tell you the one about how I reported to Sun, back in 2002 I think, that ArrayList's get(), set(), and add() methods were not inlinable, and this could be fixed by moving a single line in the code?  As a result for ten years ArrayList 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.

We have collections here and there as necessary.  But yeah, ECJ tends to work with arrays.
