Java version: 1.8.0_40-ea-b19 on Mac OS X.

I am getting the following exception, after I have scrolled in a ListView or TableView and then remove all items from it. After that modifiying the items / view is impossible!

Testcase: Scroll down a little bit, click the button.

import javafx.application.Application;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.ListView;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class TestApp2 extends Application {

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

    @Override
    public void start(final Stage stage) throws Exception {

        ObservableList<String> items = FXCollections.observableArrayList();

        for (int i = 0; i < 100; i++) {
            items.add(String.valueOf(i));
        }

        ListView<String> listView = new ListView<>();
        listView.setItems(items);
        Button button = new Button("Clear");
        button.setOnAction(event -> items.clear());
        Scene scene = new Scene(new VBox(listView, button));
        stage.setScene(scene);
        stage.show();
    }
}
