Hi,

Bug :

https://bugs.openjdk.java.net/browse/JDK-6567433

    Calling updateUI() on JList, JComboBox and JTableHeader can create 
StackOverflowErrors.
    For example -

    JList.updateUI() invokes updateUI() on its Cellrenderer via 
SwingUtilities.updateComponentTreeUI().
    If the cellrenderer is a parent of this JList the method recurses 
endless causing StackOverflowError.

Fix :

     Added a recursion guard to JComboBox, JList and JTableHeader classes.

     With this fix, UpdateUI() method in these classes does not result 
in recursion.

   Could the same issue affect another Swing components which allow to 
set a cell renderer, like JTree?

  Thanks,
  Alexandr.

    Request you to review.
