All Jar files have the same icon and it depends on the OS to show an icon on a file depending on the file type. 

primaryStage.getIcons().add(icon);

The above line will only get executed when a JVM is created for the application, so it doesn't make sense to depend on this particular piece code to display an icon :)

If you want to change the file icon, you will have to wrap the executable jar file to create a new native executable file (which depends on the OS). For example - EXE for windows. This new file will contain the image file to be displayed and the jar to be executed.

You can try using Launch4j or JSmooth for creating a wrapper file.
