It looks like the user's semantic model is inconsistent (see the unresolved proxy in the error message), but we should probably not blow up with a cryptic stack trace anyway in such cases. We could probably give a more meaningful message when the reason we could not find an interpreter is because of an unresolved proxy.

Indeed a better message could be thrown. In addition perhaps we could deprecate InterpreterUtil.getInterpreter() and use an IInterpreter reference from the Session and also prevent expression evaluation on detached object.
Scenario to reproduce with EcoreTools : 1. Create a Ecore Modeling Project 2. Create a diagram and add a EPackage 3. From the created EPackage create a new diagram and save 4. open the semantic ecore resource with the Ecore Sample Model Editor and delete created EPackage and save 5. Set the focus on last created diagram => KO we get the same exception In addition the editor should be closed as we do it when the semantic target deletion occurs in session.
