ecore_sample_with_missing_resource

Opening a modeling project with a missing semantic resource causes a silent ResourceException (I see it in my developpement environment but not in the runtime), even if the resource is not referenced anywhere besides the semanticResources tag (see sample in attachment).

Step to reproduce:
- import the project from ecore_sample_with_missing_resource.zip
- open the project
- You should not have the following exception:
