Changing XP theme while JFileChooser is open brings some rendering problems in it

- Change XP's theme to "windows classic".
- Open SwingSet2.
- Change the L&F to Windows.
- Go to FileChooser demo, Open a plain file chooser.
- Notice it have a java cup icon as dialog icon & All left panel icons are
  visible.
- Now change theme to Windows XP theme.
- Now look at file chooser, It will have one last of its left hand
  panel icon hidden(My network places) And its dialog icon(java cup) is no
  more present.
- Now close it and open again new File chooser and a proper dialog comes with
  dialog icon of java cup and all icons visible properly.
Ideally during theme change component should be able to resize properly and should not need re-initialization.
