I don't know C++, but I'd assume this is around where the issue is, as it terminates when the main method closes and not when all non-daemon threads are dead. This, however, doesn't explain the line directly after invoking launch
not running.

I never used JavaFX, but the Application class does a lot of reflection work. Maybe try to try {} catch {} everything and see if there's an unhandled exception slipping through.
Also, I believe a call to System.exit() causes the main() to not return properly as well.
from packr.
It's throwing a ClassNotFoundException
over the DesktopLauncher
class.
Which doesn't make sense, since the main
method lives inside that class; it shouldn't even need to ask for it. The program otherwise works perfectly fine outside of packr's executable, making it to the game's launcher window.
Invoking static me.scarlet.undertailor.desktop.DesktopLauncher.main() function ...

Press ENTER key to exit.
Other weird behavior is that it doesn't print out the exception if I redirected output to a text file.
from packr.
@code-disaster It's still very odd that this occurs, luckily the launch
method has alternate parameters where I can specify the DesktopLauncher class. I'll leave this issue open as this seems to be local to packr
only.
// fix
Application.launch(DesktopLauncher.class, args);
from packr.
@code-disaster The same issue still occurs in version 2.0 even with the fix that @Xemiru mentioned.
public static void main(String[] args) {
System.out.println("hello world 1");
try {
Application.launch(JavaFXApp.class, args);
System.out.println("hello world 2");
} catch (Exception ex) {
ex.printStackTrace();
}
System.out.println("hello world 3");
}
Only `hello world 1` gets outputted and the application just exits.
No exceptions occur either.

I have too faced the same issue as mentioned by the others when distributing an app that uses Java FX.
To get around this issue, I created a bash script that unzips the JDK and puts the JRE in a specific folder.
As a workaround to start the app I created a: .command, .bat, .sh - it is not pretty but it works.
@code-disaster - A suggestion would be to have a minimizeJre='skip' and distribute the JRE in full.
from packr.
@guikeller if you omit the minimizeJre
parameter, minimize is skipped. Also, this seems like a different issue, since @Xemiru wrote that he tried with a unminified Oracle JRE.
from packr.
Please try the latest version of packr and open a new issue if there is a problem.
Thanks.
