In some cases class files are used as an intermediate language,
and the source code is in some other language.  Specifically,
Kawa (http://www.gnu.org/software/kawa/) can compile various
languages (Scheme, XQuery, Emacs Lisp) to class files which
can then be compiled using gcj to native code.  This doesn't
provide very good debugging, but at least it is something.
