Right now, java packages are being built for F16 using openjdk 7, and if they are built without "target=1.6", they will fail to load under openjdk 6. (One simple example of this is xalan, see https://bugzilla.redhat.com/show_bug.cgi?id=733686 ). Some possible solutions proposed over IRC: 1) Blacklist openjdk 7 from build roots for f16 -- this means that it doesn't get tested very well, though. 2) Ensure all java packages use target=1.6 -- there's no standard way to do this across ant, mvn, javac, etc. though. You could check for 1.7 bytecode at the end of a build, but packages would still need to be individually fixed. 3) Drop openjdk 6 from F16 entirely It was also mentioned that Fedora is beginning to include some packages which build much more cleanly on openjdk 7 than they do on 6, so enforcing openjdk 6-only build roots might break some things. Other suggestions are welcome. I don't have a strong opinion about this, just a strong interest in having a sane Java environment in F16.
