Sorry I was not clear: the AWT bridge with GeoTools is working just fine.

I had performance disappointments (which is different from "problems")
when I did pure low-level SWT rendering (nothing to do with the AWT
bridge nor with GIS).
This was like four years ago, so it may have improved, but I remember
stuff like depth conversions being costly, and looking at the SWT
code, being not performed very efficiently.

I was thinking at the time that SWT would be faster because it is "native".
But on the graphics / rendering side I'm not sure it they really took
advantage of it (I'm under the impression that rather less than
Swing).
Recently I was considering how to embed native GIS rendering in Java
programs. QGIS would be a candidate since it is pretty easy to isolate
a map pane in C++, but it seems really tough to integrate it in Java.

These are just some thoughts that may be helpful for somebody trying
to develop such components in SWT. I'd be very interested in such
components as well!
