In:
org.eclipse.emf.facet.widgets.table.ui.internal.TableWidgetController.modelChangeAdapter.new AdapterImpl() {...}.notifyChanged(Notification msg)

notifyChanged calls an asynchronous redraw on the widget. This results in the attached exception when the table closes before the asynchronous event has had time to run.

The good practice is to check that the widget is not disposed before trying to access it in an asynchronous event.
