The cause is in org.eclipse.sphinx.emf.resource.ExtendedResourceAdapter#unloaded(EObject), line 114, where the fields are cleared by reflection.
Comment 1 Stephan Eberle CLA 2011-03-09 07:21:19 EST 
Fixed by excluding MinimalEObject#eFlags and #eStorage fields from reflective nullification. This makes sure that "cleared" MinimalEObjects can still be converted to proxies and identified as such.
