JFileChooser is not serializable in Motif while it can be serialized in other L&F's
Steps to reproduce:
1) Run the attached test TestSerializeFileChooser
2) Change L&F to Motif using Menu "Look And Feel"
3) Click on button "Serialize FileChooser"
4) It will throw Exception in console
5) Now try serializing in someother look and feel it will
   give message ""Successfully serialized FileChooser" on console
Tested on Tiger b30
