I know Ken pretty well. Hes been an advocate for performance feaatures in the VM (he really is the father of Native Byte Buffers) as ewll as having been a long standing advocate for Sun getting behind OGL.
He doesn't happen to be the same guy I read about ages ago, that pushed hard for the 8 basic datatypes to be included in the JLS, rather than make Java a "purely" OO-language (i.e. only Object's allowed).
Whoever that person is, I've spent most of the last 8 years simultaneously cursing and worshipping them. Cursing for some of the hacks that Java *still* has to try and accomodate having basic datatypes in an Object world (although in most cases I believe they were less of an inevitability, and more a reflection that not everyone was enamoured of the BDT's - and perhaps rather hoped they'd go away?), and praising for their very existence (life would be hard if you couldn't have new int[ 10000 ][ 10000 ]).
Uh, yeah, and the [ ] type is also highly appreciated. If everything had to be a Collection... Argghhhh!
