JFace TableViewer shows two tooltips - custom and default

I got a strange situation here where I need help.

I create a fairly simple JFace Table using a

. When you do nothing more, you can see the following behavior: when a cell's text is too large, a tooltip showing the complete text will appear after a short wait. That's normal behavior and I guess that the native controls draw these tooltips.

Now I added my own custom tooltips, using

ColumnViewerToolTipSupport.enableFor( tableViewer, ToolTip.NO_RECREATE );

And delivering a (different) text using
method of a label provider.

That works - almost. I got one problem: sometimes (not all the times!) first, the native tooltip appears and shortly thereafter my custom tooltip is drawn on top of it, like shown in this screenshot:

I have no idea how to effectively disable the native tooltips each cell wants to draw. It's ugly as hell the way it is...

Any clues for me? Thanks!
