Important: JDK7 Changes of Note as of 10/15/2013
Oracle released a new version of the JDK 1.7u45. This has been reflected and tested in the site.pp file. If you have an older JDK you will need to modify site.pp only. The JDK7 Puppet module does not need to be modified.
site.pp is located here:
https://github.com/matthewbaldwin/vagrant-wls12c-centos64/blob/master/puppet/manifests/site.pp
You will need to modify this for your particular jdk that you download.
