Convert .jar to an OSX executable?

Question

I made a Java application which I would like to distribute on Windows, OSX and Linux without distributing a jar file. I used the great Windows exe wrapper http://launch4j.so

Github user Jorl17 made an excellent Python script called jar2app that does this with one simple command. It even lets you customize the app icon.

Just install it, follow the instructions, and you get the .app file.
