Good to hear, I wish you success. I understand on Windows/Mac you have to package the JRE, but I'd recommend considering using the distro for that functionality on linux - it's generally frowned upon to re-package stuff in the official repos. I think an AppImage would generally be worse, I'd rather be able to use my system's JRE and libraries. I'm on Arch, so if you provide an archive of the application we can work with that. If you really want to go above and beyond for Arch users you could make and publish an AUR package.
