I had saved off the Participants list as HTML and added my bot to it and
hosted it on my own web server, then changed roborumble/roborumble.txt:
UPLOAD=NOT
ITERATE=NOT
PARTICIPANTSURL=http://<myserver>/Participants.html
but it doesn't seem like those changes did any harm.

I do see CodeSizeCalculator.class inside libs/robocode.core-1.9.0.0.jar.
But that's not in the -cp arguments in roborumble.sh. If I try to add it, I
get

Am I going to wind up having to add every .jar in libs to the classpath
arguments in roborumble.sh?

Ohh... this definitely something that needs to be fixed before releasing
Robocode v1.9.1.0 so it works the same way as it did for 1.8.3.0 and
earlier.

I might create an alpha version for you later tonight (Danish time) so you
can try it out.

Thanks for bringing this issue to attention!

Cheers,

Hi again,

I have made a fix for it, which you can try out here: Robocode 1.9.1.0
Alpha 2<http://robocode.sourceforge.net/files/robocode-1.9.1.0-Alpha-2-setup.jar> (not
a real release).

Cheers,
- Flemming
