why is java not reading the correct deployment.config file??

We have a 5-server RDS farm on Win2k12 R2.
All the servers have Java installed on them.
Group Policy redirects AppData (as much as it can) to the user's folder on our file server.

I read all the numerous instructions about how to put deployment.config into C:\Windows\Sun\Java\Deployment on each RDS 
server and deployment.properties and exception.sites into an accessible network share, referred to in deployment.config and exception.sites, respectively.

deployment.config says:

deployment.system.config=file\://server/software/java_files/deployment.properties
deployment.system.config.mandatory=true

deployment.properties says:

deployment.webjava.enabled=true
deployment.security.level=HIGH
deployment.security.level.locked
deployment.expiration.check.enabled=false
deployment.user.security.exception.sites=file\://server/software/java_files/exception.sites

exception.sites contains just one website URL

What is happening and I don't understand why, is the users start Java and they get a deployment.properties file created in the 
RDS server's local user profile in C:\Users\username\AppData\LocalLow\Sun\Java\Deployment...which does not even have the desired deployment properties nor the exception.sites involved.

HOW do I get Java to work as it's supposed to?? -- read the deployment.config and use the referenced deployment.properties file??

I could live with Java using the local user profile directory if it can't be properly put into the appropriate redirected AppData folder location.

Incidentally I've seen this same problem with a XenApp 6.5 server farm, I know I'm not imagining things. :)

Thank you, Tom
