Creating your own bits in any app's App folder is never supported and will always be wiped out except under very specific circumstances. This would include specific apps that require add-ons/plugins to be installed in a specific folder within the App directory and won't work from anywhere else (like App\AppName\plugins). These directories are specifically preserved.

The reason for this is that most apps will have specific files added and removed as they progress from version to version and having a file from an older version of an app, like a DLL or configuration file, present in the newer version of an app can cause undesirable results (instability, crashes, graphic defects, etc). The way to address this without having to track what files should/should not be present in the current version vs every previous version ever released (so users can upgrade from any previous version to the current one) is to wipe the App directory.

If there is a path within Java for add-ons that we should specifically be preserving, please let us know. But generally, Java apps should be self-contained and not require bits be added to the VM itself.

Sometimes, the impossible can become possible, if you're awesome!
