Step to reproduce :-
------------------
1) Run SwingSet2.
2) Select JFileChooser demo.
3) Click on 'Show Plain JFileChooser' button.
4) Click on 'Detail view' Button.
5) Observe that 'Name' column back ground is not complete touching the column separator. Actually it should be like native ( Solaris developer express ). This can be consider as a bug or an RFE . The reason for RFE is that it gives a good Look .
I have attached a screen shot of both the native & nimbus lookAndFeel.
