Small Java code to reproduce problem

When using GTK3, SWT tables report a 0 pixel header height if headers are enabled on their first request to calculate its preferred size. In result a table with a single line (+ header) will be displayed so small at its preferred size that the TableItem is almost not seen and cannot be made fully visible using the very small scrollbar.
On GTK2 the table is properly displayed providing room for the header, the table item and about half of a further empty line.

The attached source code reproduces the problem.

Hi Christian,

I wasn't able to reproduce this problem running the latest GTK3 on Fedora 25 vs GTK2 for both X11 and Wayland. Are you running the latest SWT builds?
Comment 2 ChristianR CLA 2017-03-22 14:51:09 EDT 
I am using the SWT Libraries that I have taken from my Eclipse RCP Developers Version (4.6.2.)
The files are named:
org.eclipse.swt.3.105.2.v20161122-0616.jar
org.eclipse.swt.gtk.linux.x86_64.3.105.2.v20161122-0613.jar

I am running an xubuntu 16.04.2 LTS but installed also some KDE stuff.

I can't reproduce this issue either. Can you try on GNOME with GTK3.22 and 4.8?

Marking as WORKSFORME, please open if you find otherwise on 4.9M2/GTK3.22.
