NetBeans 6.7 JavaFX plugin on Windows XP.

Community people reported the following issue. It looks
JavaFX application without GUI (without exit button),
NetBeans can not kill the process.

1. Create new JavaFX project

2. Remove contents

3. Just add the following code

import javafx.animation.Timeline;
Timeline {}.play();

4. Run
5. Kill the process from NetBeans by click x button of process window

However, it's still running and next run will not succeed - build error
happens because the running process grabs the jar files.
