I'm presenting at CUFP and will spend my time in Victoria... sorry.

It looks like the JVM Language Summit runs Sept. 24--26 and SIGPLAN's
Commercial Users of Functional Programming workshop is the single day
of Sept. 26th just after ICFP (Sept. 22--24). Anybody interested in
both and/or contemplating splitting their time between them?

Yes, that's basically it. To save ourselves future pain moving to JSR292
or just refactoring our call-path, all the Java-implemented Ruby methods
are bound via generated method handles. So a method on RubyString might
look like this:
@JRubyMethod(name = {"[]", "slice"}, reads = BACKREF, writes = BACKREF)

We're talking about source-level pre-processing, which is to say
pre-bytecode.
An example problem is stuff that constructs the classpath which the
compiler expects to be set before it is called, as with dependency
managers. Naturally that is a little bit of chicken-and-egg problem if
your configuration for the dependencies is in the source.

Have BCEL or ASM or any of the bytecode toolkits taken up the slack on some of this yet?

Then perhaps using the Eclipse APT is the way to go:

Although since javac, apt, and friends are in OpenJDK, that would
probably be a better starting point:

I've considered doing the same, but the compiler I need to hook into is
javac, not JRuby's compiler. Groovy has a different situation because
they want to process annotations in Groovy code, not in Java code. I
need cross-JDK annotation processing of annotations in JRuby's Java
code, unfortunately.

Well, it probably isn't useful for JRuby, but Groovy had a similar
problem but solved it by implementing Java 5 Annotations processing as
part of it's compiler. There is even an example by Danno Ferrin
(Grape's "@grab" annotation) which hooks into an early compiler phase to
pull in classpath dependencies. I believe all this Groovy compiler and

Annotation processing without Sun dependency

Ok, I've got a problem. In JRuby 1.1.3 we started using a compile-time
annotation processor to pre-generate a bunch of code. This has helped
startup time, since before we did this processing at runtime using Java
reflection classes, and just using those classes increased both memory
and startup time.

A long time ago I came across [link] which looked
promising, but nothing ever happened to it beyond 2001/2002. It's been a
while since I gave it a bash so not sure what state its in (downloading now
to look at).

Cool stuff. Just out of curiosity...anyone looking at putting
Smalltalk on the JVM using the Da Vinci Machine?

Some more NestedVM factoids: NestedVM does a pretty good job outside
of a couple of known areas (like anything involving floating point,
the last time I looked). In fact, one of the early conference papers
on it was typeset using a build of TeX that had been compiled from the
C source through NestedVM and into bytecode, where it was run on the
