I assume you mean kaffe's CVS head. I updated my installation to this.

Thanks a lot for this, it did get me a long way! :)

However, it's still not really usable. Still on Eclipse 3.0.1 (are there any
newer experimental releases I should try?), eclipse starts loading and asks
me where I want my workspace directory. Fine so far! However, past this, I
get an error dialog box, and on the console I find this stack trace:

I press OK in the dialog box, and Eclipse actually does start up, opening my
current project in Debug perspective (at this point it also gave a
ClassCastException trying to create the editor window for one of the .java
files, but I was able to open it later). I have to say it's not really
usable, though, many strange things :( One of the worst being it cannot
save files:

...

The code completion feature also does not work, but no exceptions either.
The addictive QuickFix feature was also missing for some reason, and when
trying to run a JUnit test, I was told it couldn't find any.

I'd help debug all this if I had the time (and skills :), but unfortunately
I don't. So I'm back on SUN's j2se for now, for those applications that
need it. I appreciate your help!

Thanks,
Haakon.
