You probably have something in the CLASSPATH that kaffe doesn't like. 
1.0.7 had quite bad CLASSPATH handling and would ocassionally get 
confused about the location of it's own core classes.

Could you try the latest developer release, 1.1.2? It has several 
imporvements to it's CLASSPATH handling and should be quite hard to confuse.
