[External] : JavaFX launcher in JDK

[Christopher Schnick]

I was just playing around with the launch process for JavaFX and 
encountered the known issue "JavaFX runtime components are missing, and 
are required to run this application" when the Main class extends 
Application.

Then, I wanted to look where this message is printed from and how the 
launch process is handled to see if there are possible improvements there.

Now if I see this correctly, the non-modular JavaFX Application 
launching is done from the JDK itself? The code is still included in the 
JDK in java.base at sun.launcher.LauncherHelper.FXHelper and not 
decoupled from the JDK. So this can't even be changed in the jfx codebase.

Is this intentional or a leftover, i.e. would it be possible to even 
change this or is that some legacy thing which can't be changed?
