A DESCRIPTION OF THE PROBLEM :
If a JavaFX application is launched with parameter -splash:path_to_image, Platform.exit() won't be able to exit the application in a clean way and the System menubar is OSX will stop to be supported.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1 - Create a hello world in JavaFX with a menu called "File".
2 - Be sure to have menuBar.setUseSystemMenuBar(true) so the menu will display in MacOS menuBar and Platform.exit() in your exit() or stop() method and add it a QuitHandler.
3 - Run it using java -cp ... , app here will run normally , exit normally and "File" menu will be displayed exactly in the system menu bar.
4 - Run this time with a splash screen , "java -splash:path_to_img -cp ..."
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
1 - A splash screen is displayed before at startup
2 - Menu "File" is displayed in the OSX system menu bar.
3 - When Quit is clicked , application exits without any exception in the log.
ACTUAL -
1 - A splash screen is displayed before at startup
2 - Menu "File" is displayed in the OSX system menu bar.
3 - When 'Quit' menuItem is clicked , application exits with exceptions.
ERROR MESSAGES/STACK TRACES THAT OCCUR :
If application is launched from the command line as described before , it shows the following exception on exit :
