This issue is similiar to bug 72187. This time a different exception is thrown 
if a JLabel is clicked thru JLabelOperator.clickMouse() and the mouse click 
causes the JLabel to become invisible.

From what it seems is that JLabelOperator.pushMouse() does not cause the 
exception. But I also need to have the clickMouse() functione working.

Sample code looks somthing like this:
---
jLabel = new JLabel();
	jLabel.setText("Sample Label"); 
	jLabel.addMouseListener(new java.awt.event.MouseAdapter() {
	public void mouseClicked(java.awt.event.MouseEvent e) {
	        jLabel.setVisible(false);
        	System.out.println("mouseClicked()"); 
	}
});

The Exception thrown is:
org.netbeans.jemmy.JemmyException: Exception in Choise 
expanding
