[SOLVED] JavaFX: Exception in thread "JavaFX Application Thread" java.lang.NullPointerException: Cannot invoke "com.sun.prism.GraphicsPipeline.is3DSupported()"

JavaFX: Exception in thread "JavaFX Application Thread" java.lang.NullPointerException: Cannot invoke "com.sun.prism.GraphicsPipeline.is3DSupported()"

I am programming a JavaFX Application which shows an undecorated stage. To close my application, I use a button, which calls the method System.exit(0); The problem is that I get sometimes this exception without links to my code when I use it:

Exception in thread "JavaFX Application Thread" java.lang.NullPointerException: Cannot invoke "com.sun.prism.GraphicsPipeline.is3DSupported()" because the return value of "com.sun.prism.GraphicsPipeline.getPipeline()" is null

Solution

call Platform.exit() instead of System.exit();
