I wanted to set the dock icon in Mac and expected it to work the same way as setting the taskbar icon in Windows 7, namely with:

stage.getIcons().add(myIcon).

However, it doesn't work. Instead the default Java coffe cup icon is in the dock.

After googling it turned out, that it can be done with a 3rd party library: com.apple.eawt.Application#setDockIcon

In fact that works, but I'd like to see stage.getIcons().add() work the same way.
