I am looking for it too, it was in the google code svn.
As I read, the end of google code provided an auto-migration of “all” content to github, so… it seems, not all files were migrated and some got deleted…
As soon they restore it from a backup I would like to know too.
For the while I am using jdgui but the generated sources doesnt match the lines while debugging, I dont know why… so it didnt help.
