The whole idea of using Java is to support something other than Windows. I use a Mac and all companies I worked with had all common OS's on desktops. The edge cases are the problem. This isn't a product for other engineers. At least not engineers who have experience with JVM conflict issues.

For end users and to get a smooth installer experience there's a huge distance. Customizing the installer in the packager is a nightmarish problem... Or at least it was the last time I did it.
