Hi Ketan,

Are you aware of the following error? Should we make a bug out of it?

I am trying to run SWTBot in headless mode on a Mac OSX 10.6 64 bit and I get:

org.eclipse.swt.SWTException: Invalid thread access

The thread that dumps this stack trace contains the main method, and is
the main thread. It appears that there is something else that is
creating the display in a different (non-main) thread before the
UITestApplication starts it.

Also could you check that you've set the -XstartOnFirstThread jvm flag
on the jvm when running headless ?
