Why x?

Maybe that should be a snippet?

I don't know if that's an issue, but the source code bundles generated 
source by java-cup and jflex. I've tried to bootstrap both correctly, 
but there is no version of jflex you can build without jflex and cup. I 
have a recipe for java-jflex and java-cup that are built without 
pre-generated source, using two bootstrap jars. Then, I could use them 
to build other packages that I need for the future maven-build-system. I 
wasn't able to build java-jflex with the latest java-cup.

Do you want me to send these recipes for comparison?
