1 + 1 = 1.7
First Andrew Hughes made Sun GPL javac compile and now Andrew Haley made it run with GNU Classpath and gcj/gij. Go Team!
Peter von der Ahé from Sun posted a update to upstream javac. It would be nice if the changes needed and made by Andrew and Andrew also found their way into some future update. Apparently Sun is working on updating the contributor agreement to mention that all contributions will (also) always be available as free software in the future which would be great (not that I think it would make much sense for Sun to keep a separate proprietary-only fork including outside contributions, but it is always a good thing to have such things explicitly put on paper).
