It seems you are correct that eliminating the about.name <http://about.name/> appears to have no impact. Eliminating -Dapple.awt.application.name <http://dapple.awt.application.name/>=HalfPipe and the About menu item no longer shows the application name but rather the unpackaged main class name. The About window is still correct. It includes the application icon, the application name (valid) in bold. Also, Version and Copyright it appears to get from the application Info.plist. Rather a nice default. I could post a screen shot somewhere? Possibly something has been cached for the app by Apple from some time ago? Or I still need to figure out where this comes from.

Fwiw, I did a little more looking at this.

It seems this…

_AppEventHandler
openCocoaAboutWindow(); // if the handler is null, fall back to showing the Cocoa default

Is what gets the default window that I am seeing.

It would then almost seem like a javaFX application could do something like…
static {
		java.awt.Desktop.getDesktop().setAboutHandler(null);
	}

Might work but it doesn’t.

You can’t compile directly against com.apple.eawt anymore…
JDK-8160437 : com.apple.eawt.Application is not exported

So I don;t know if that could work-around.

I might wonder if it would be easier for the jdk side to get the Desktop invocation to work rather than javaFX rework all that Apple and the jdk already has done from scratch?

But currently there appears to be no way to include this functionality for a javaFX app. 

Although, I haven’t asked on the javaFX list. Maybe they already figured all this out
