I'm pleased to report that today's Kaffe CVS can run Freenet without
crashing!

However, it is also not working correctly.  The node initializes
properly, and seems to respond to web interface requests (servlets).
However, any time I attempt to view an actual Freenet document
("Freesite") through the web interface, I get an error like this
one in the logfile:

I also tried downgrading my Freenet build to a month-old one just to
see what would happen; I got the same results.  My logfile is chock
full of these "Negative bit address" errors.

Tech stuff: Freenet build 6043 or 593, Kaffe CVS from 2003-06-02,
on OpenBSD 3.2 x86.  Kaffe was configured with "./configure
--with-includes=/usr/local/include --with-libraries=/usr/local/lib
--with-engine=jit3 --enable-debug".  Freenet was built with jikes 1.14
on a Debian "unstable" x86 box.
