Hi,

For anyone who's interested in this kind of stuff, I just uploaded my
pure-ruby toy JVM to Rubyforge. It's obviously very slow, but can be
useful for seeing how things work or debugging generated classes that
won't verify. It can do some reasonable class-dumps and execution
traces, too. It's probably about 70% complete, with most instructions
implemented, and currently has some integration with the GNU Classpath
runtime library.
