When using "Load resource" in the Sample Reflective Ecore Editor and using a platform:/plugin URI (e.g. for development version of registered packages), the user can change the model since neither org.eclipse.emf.edit.domain.AdapterFactoryEditingDomain.isReadOnly(Resource) nor isReadOnly() implementation of the anonymous AdapterFactoryEditingDomain class in org.eclipse.emf.ecore.presentation.EcoreEditor.initializeEditingDomain() returns true for such URIs.
Is this intentional?
Saving the editor after modifying such resources also results in an exception:
