I think, in some way, you have set SWT debug options on the server.
Check if there is the .options file with the following lines:

org.eclipse.ui/debug=true
org.eclipse.ui/debug/swtdebug=true
org.eclipse.ui/debug/swtdebugglobal=true

Few m2e tests started to fail recently on our CI system. These
particular tests require Eclipse Workbench, which apparently fails to
start due to some SWT/GTK misconfiguration. The same tests pass on my
OSX laptop and Linux desktop, so the problem must be with our CI system,
which runs centos 6.5, btw.

The CI system has GTK2 libraries installed, but forcing SWT_GTK3=0 does
not make any difference.

I see the exception below when I enable SWT debug log, but this does not
tell me anything.

Has anyone seen this kind of problem before? Any suggestions how to
troubleshoot this further?
