Yay open source!  Kaffe is really quite nice.  I hear they've even
fixed the lack of BigDecimal, etc...

I'd recommend against reading them.  They will make your brain dirty,
in two ways: you will have to look at Sun source code (green_threads
was not implemented by blackdown) and you will end up being unsuitable
for cleanroom efforts such as Kaffe and Classpath.

Yes.  Sign an NDA with Sun and I'm sure they'll be happy to give them
to you.  If you're not on the blackdown team, you can't get the code
which they have written, because Sun owns it under NDA.

I don't think I will have any success with convincing you not to do
this, but PLEASE consider doing something other than working on Java,
especially Sun's Java.  Java-the-language is really just dumb (no
function pointers, no macros, no closures ...) and java-the-platform
is so non-functional it's a wonder anyone uses it at all.

(for those of you who follow Sluggy Freelance) Stay good, Chris, stay
