Java Preferences

Utilties/Java Preferences settings are stored in the following user-level location :

~/Library/Caches/Java/deployment.properties

In order to centrally manage this file, you would add the settings you desire to a user logon script or LaunchAgent.

A good example of why someone would need to manage this file is if you are using .PAC files to control proxy settings. Currently, JVM has a bug where it may not correctly read your .pac file causing java applets to fail.
