[platform-swt-dev] Problems with TableViewer VIRTUAL on MAC

[Alessandro Assab <aassab@xxxxxxxxxxxxx>]

Hello,
I have a problem with TableViewer VIRTUAL on MAC. When I have more than
1751 lines in my table the setSelection method don't work correctly only
on MAC. In particular, the setSelection method select the correct item
in the table but dont show it. Is there an open bug?

I attach a simple snippet code to verify problem.

Thanks for your attention.
