Setting Java 7 as default Java using the cookbook

Hi Chefs,

Re: the Opscode Java cookbook. Specifically:

Does anyone know why it only agrees to run update-alternatives when the java version gets a priority of 1061? This seems to be preventing Java 7 from being set as the default on my system because apt (or at least I think it’s apt) gives it a default priority of 1051. Is it safe to override this or will I encounter dragons?
