Description
I have a frame to which  i have added a button. The whole process i am doing in toolkit thread  as follows
 Toolkit.getDefaultToolkit().getSystemEventQueue().invokeAndWait(new Runnable() {
	public void run() {
		// create a frame & adding the button to it.
	}
}

When the frame is visible , i press on the button. I see the following warning.
