[jbosstools-dev] [m2e-dev] Fwd: any swt/gtk experts around?

Well, yes, I did enable SWT debug to see why m2e tests are failing. As
you can see from the stack trace, Eclipse Workbench fails to start due
to the SWT problem, which in turn results in test failing later on.

I did some more looking into this and the problem appears to be specific
to headless X servers (both VNC and Xvfb are affected) on Centos. The
tests pass on Ubuntu, both in proper GUI session and using Xvfb and in
Centos GUI session. I am guessing one of GTK libraries shipped with
Centos misbehaves but don't know how to troubleshoot this further.
