Failed to go to FOSDEM, meaning I missed lots of the OSS java people, but as oneof the things I've been sporadically trying to follow is native eclipse for FC2 I have some good news. I'm happy to say that the latest ant that is in rawhide fixes the issues I had with the naoko ant and libgcj-ssa (multiple classpath entries for .so in an executable).
I'm rebuilding against gcc34 packages and if that all works I may host a yum repo. I'll build on ppc later too. Then to work on rpm-java. I may also try and package native jython too.
