Broken how?

The class Test is not a stand-alone class - it is not a
"module class"  The module class (by default) is a class
that matches the name of the source file scratch.scm
- i.e. scratch.class.  Things might work better if you
rename scratch.scm to Test.scm so they match.

You might want to (re-)read:
http://www.gnu.org/software/kawa/Module-classes.html

This is a source of confusion and a semi-frequently asked question.
It might be worthwhile for the Kawa compiler to emit some extra
code in Test.class's static initializer so it forces initialization
of tyhe module class scratch.class first.
