Hi,
Thanks Alex for pointing out there might be more components showing similar
behavior.
Two more components are identified which may cause this recursion in
UpdateUI() method - JTree and JTable.
Now, total 5 components ( JComboBox, JList, JTree, JTable and JTableHeader)
are fixed.
Please review the updated webrev :

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.
