Since an update to version 1.6 and Hudson 1.299 the DISPLAY variable is not set
during the build process anymore.
We try to test a SWT application wich requires this env-var or refuses to start.
Below is first the SWT exception - with a cryptic error message but this means
not DISPLAY is found.
Below the trace are all system properties printed by Sytem.getProperties().list(...)

Exception in thread "main" org.eclipse.swt.SWTError: No more handles
