Yeap. It's preferred to vendor a JRE (non-system JRE) inside your app (which is basically just extracting it to some dir you always control), which doesn't conflict with whatever else is on the box (no registry settings, /etc/profile or common locations like /usr/some/unix/path/to/system/jre ), and auto-update your app which includes updating the JRE. This is how to deploy a supportable app, which reduce support tickets about "you broke our apps, our IT department is going to call our VPs and is going to call your VPs" and pre-sales issues like "we can't buy this because we can't change JRE versions."
