Update java packages for Fedora systems

The java package on Fedora is currently java-1.7.0-openjdk for their basic
java, and java-1.7.0-openjdk-devel for a development set. Fedora 16 had
java-1.6.0-openjdk, but it has been EOL for a long time. This commit updates
the default java for Fedora to the 1.7.0 package.
