Thanks for the reference. I have printed it and will read it over my
upcoming vacation. (Yes, I'm a geek!) One question, how do we know this
is on the System i's JVM? Seriously, not trying to be a pain. The
preface to the article mentions the " IBM Developer Kit for Windows(tm),
Java Technology Edition, Version 1.1.7."

I suggest an email to Blair Wyman. Blair has forgotten more about Java, especially for the System i, than any of us will ever know. I suspect he'll be more than happy to point you to other things.

This is from back in 2000, and it's just scratching the surface

Why do you say it's just scratching the surface? I know it's old, and
I'm sure things have improved, but what is there to _show_ me the
improvements? "It's in there" might cut it for pasta sauce, not for
code! There's too much, IMO, on the System I that we're told "we don't
need to worry about" or "it's in there" that we can't see/tell for
ourselves. I want to understand at a detailed level and see.

Hey, I'm not trying to start a "whose is bigger" argument, even though my statement that IBM owns system programming could be construed that way. Honestly, I just thought it was common knowledge that IBM writes the best system code, but if you disagree, I'm not going to fight about it.

If you're truly a geek, start looking up Toshio Suganuma's publications. I think Toshio is one of the honchos over at the Tokyo lab, where the JIT stuff is done. Unfortunately, some of the REALLY cool stuff is not available for free. But here's a good one:

As for incorporating older technology, remember the CLR has been around
for a while too. What I found nice was actually being able to see the
generated code and know that it had been done.

Not slinging things, Walden. Really! I'm just pointing out that perhaps the JIT compilation techniques in the CLR might not exactly be "revolutionary" or even new stuff. This wouldn't be the first time; Microsoft is very good at assimilating other technologies.
