Description
Since JDK 1.8.0_60, a folder named .oracle_jre_usage gets created in the home directory. This folder and the files inside it are created by the Java Runtime Environment to track the last time a JRE was used. This information is very important in understanding what JRE installations are currently being used on the system.

On Windows, this folder gets created under either `C:\Users\<username>\AppData\Local or C:\Users\myName\AppData\Roaming` depending upon whether the user is local, or is a network user.

Writing content in this folder over the network on Windows can introduce performance overhead. This problem has been fixed with bug JDK-8134300. With this fix .oracle_jre_usage folder gets created under `%ProgramData%/Oracle/Java/`
