Not quite there yet (last time I checked a month ago), but moving
along.  Most things worked, but some programs that worked under a
standard jdk would die, and java 2 compatiblity was still being worked
on.  Two others open source ones are japhar (www.japhar.org) 
and jasmine (can't find the reference to it, it was based of gnu
classpath, as I recall).

I've been happy with these and reported to be faster than Sun's.
Also, Jikes is a compiler (to bytecode), not a jvm, so you'll need that.  It's open
source under IBM's IPL.

Careful, IBM's Visual Age is different than MS's Visual blah.  On
Windows, Visual Age is a pig for memory, but you get a really neat
development environment, including being able to do wiring diagrams of
the program, and have it generate it.  It also generated standard
code, that ran on any platform with a jre.  Part of the memory hog
probably came from the core being IBM's Visual Age for Smalltalk.
