I have been reading about project centennial (<https://msdn.microsoft.com/windows/uwp/porting/desktop-to-uwp-root#preparing-your-desktop-app-for-conversion-to-uwp>), and it occurs to me that there are many legacy line-of-business apps that are written in Java (not to mention Python/Tkinter, *insert language/gui toolkit here*, etc). 

I can see a benefit in being able to market/distribute these through the Windows store (either internally for an enterprise or to the general public).

I was wondering if it is possible to turn a Java application into an AppX bundle (possibly using something like launch4j as an in-between step)?
