Textures leak when window is resized

The test below, when left running for some time (several minutes on my machine) starts to throw exceptions:

import javafx.animation.KeyFrame;
import javafx.animation.Timeline;
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.stage.Stage;
import javafx.util.Duration;

public class Test extends Application {
    @Override public void start(final Stage stage) {
        stage.setScene(new Scene(new Group()));
        stage.setWidth(400);
        stage.setHeight(400);
        stage.show();

        Timeline anim = new Timeline(new KeyFrame(Duration.millis(10),
            new EventHandler<ActionEvent>() {
                public void handle(ActionEvent ev) {
                    stage.setWidth(1000 - stage.getWidth());
                }
            }));
        anim.setCycleCount(Timeline.INDEFINITE);
        anim.play();
    }

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

The exception is
java.lang.NullPointerException

I've found something suspicious in PaintRunnable.run():
311 disposePresentable();
312 presentable = factory.createPresentable(scene.getPlatformView());
createPresentable() creates a SwapChain and a RTTexture, but disposePresentable() disposes SwapChain only.
