   Preondition Violations

   Type org.eclipse.core.resources.IWorkspaceRoot of variable workspaceRoot does not match with type org.eclipse.emf.common.util.EList<org.eclipse.emf.ecore.EAttribute> of variable eKeys
   - Make classes org.eclipse.core.resources.IWorkspaceRoot and org.eclipse.emf.common.util.EList extend a common superclass
