NullPointerException happens if a ListView is resized many times

NullPointerException happens if a ListView is resized many times

(JavaFX 2.0 beta b34 + JDK 1.6.0_b25 + WinXP SP3)

How to re-produce:
1. Start the sample app(codes below)
2. Drag the right-bottom corner of the app window to resize the app window
3. Keep moving your mouse here and there a little quickly, resizing the app
   window drastically
4. If with good luck, within 1 min, you will see below exception
   (sometimes I could re-produce it within 5 second, but sometimes, 3 minutes)

The exception is like below:

java.lang.NullPointerException

Below codes can be used to re-produce:

import javafx.scene.Scene;
import javafx.scene.control.ListView;
import javafx.scene.layout.Pane;
