Table Header are not showing the RollOver effect unlike Native Cinnabar


Steps to reproduce:
--------------------
1) Open SwingSet2, change the LAF to GTK and goto Table Demo.
2) Take the mouse over the header. No rollover effect.
3) Now open the Search File application on the Cinnabar and search for something, the search results will displayed in a Table.
4) Now take the mouse over the header, you will see the rollOver effect.
I have used Cinnabar b14 and JDK b59.
