Comment 4 for bug 504848

To compile katta:

git clone git://katta.git.sourceforge.net/gitroot/katta/katta
cd katta;
ant dist

The result will be in build/katta-core-0.6-rc1.tar.gz. Just take the katta-0.6-rc1.jar out of it. (http://trendiction.com/tmp/katta-core-0.6-rc1.tar.gz)

The error still persists, also with the new jar from the zip file above.

Btw, play will just start fine, if I build a jar of all my play source application files first, and the put that jar into the play lib dir. But I loose JIT editing of the source files then, and have to copy jar files around on each change.
I couldn't check if katta works in that combination as I don't have katta running on my develop machine.
