Shift+Tab causes the JFileChosser to behave vague
Steps to reproduce:
1) Run SwingSet2 on Mercury with -Dswing.gtkthemefile=<Your .gtkrc File>. Change the Look And Feel to GTK.
2) Go to FileChooser Demo.
3) Tab to Text field.
4) Write something in the text field say 'a'
5) Now press shift+Tab.
6) The contents of the 'File' list goes away and the focus is also not transfered to the file list which should be transfered.
7) After this click on any folder, it does not show any files in that folder.
