   Preondition Violations

   Type org.eclipse.emf.common.util.EList<org.eclipse.emf.ecore.resource.Resource> of variable resources does not match with type org.eclipse.emf.ecore.provider.EStringToStringMapEntryItemProvider of variable eStringToStringMapEntryItemProvider
   - Make classes org.eclipse.emf.common.util.EList and org.eclipse.emf.ecore.provider.EStringToStringMapEntryItemProvider extend a common superclass
