What is wrong with my GMF generated diagram code?

Question

I have generated a non-RCP diagram editor with GMF. My Eclipse version is: Indigo Service Release 2. When I would like to Run as an Eclipse Application it fails and the following error log is generated:

Answer 1

I have checked the org.eclipse.swt and the org.eclipse.core.net bundles at the Run as Eclipse application configurations and it works now.

Remark: it is worth enabling Validate plug-ins automatically prior to launching (Run configurations->Plug-ins>Validate plug-ins automatically prior to launching tick)
