Java 7 Update 51 - Populating the Exception Site List on upgrade deployment?

So Java 7u51 is out with a new feature, Exception Site List. This is stored in C:\Users\username\AppData\LocalLow\Sun\Java\Deployment\security\exception.sites.

Any ideas on how to populate this for all users during the upgrade via Patch Manager? C:\Users\Public\AppData doesn't exist, so that's out...
