Description of problem: A zero-day vulnerability has been discovered in openJDK 1.7. 1.6 is not affected. See http://www.kb.cert.org/vuls/id/636312 for details. I'd like to drop back to openJDK 1.6 on my Fedora systems, but I can't, because the RPM isn't in the repositories.
Fedora 17 does not include openjdk 1.6, only openjdk 1.7. bug 852958 has been filed against Fedora 17 to track the resolution of this flaw in openjdk 1.7.
