      Example code. The problem can be "fixed" by avoiding an empty SwingNode.

      import javafx.application.Application;
      import javafx.embed.swing.SwingNode;
      import javafx.scene.Scene;
      import javafx.scene.control.ComboBox;
      import javafx.scene.layout.VBox;
      import javafx.stage.Stage;

      public class NullSource extends Application
      {
        public static void main(String[] args)
        {
          Application.launch(args);
        }
        
        @Override
        public void start(Stage primaryStage) throws Exception
        {
          ComboBox<String> cb = new ComboBox<String>();
          cb.getItems().setAll("a", "b", "c");
          
          SwingNode sn = new SwingNode();
          // SwingUtilities.invokeLater(() -> {
          // sn.setContent(new JLabel("JLabel"));
          // });
          
          VBox root = new VBox(20, cb, sn);
          primaryStage.setScene(new Scene(root, 500, 300));
          primaryStage.show();
        }
      }
