REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
Supply a jpg or png like https://duke.kenai.com/wave/.Midsize/Wave.png.png in root of cp and start java with command like java -splash:Wave.png.png de.test.SplashTest


package de.test;


import javafx.application.Application;
import javafx.stage.Stage;

import java.awt.*;

public class SplashTest extends Application{

public static void main(String[] args) {
launch(args);

}
public void checkSplashUpdate() {

SplashScreen splashScreen= java.awt.SplashScreen.getSplashScreen();
splashScreen.createGraphics();
splashScreen.update();
splashScreen.close();
                       // calling splashScreen.update() instead of close() a second time also
                       // kills the app, because internally it also calls SplashLock
}

@Override
public void start(Stage primaryStage) throws Exception {
checkSplashUpdate();
}

}
