   Preondition Violations

   Type org.eclipse.emf.ecore.resource.URIConverter of variable defaultURIConverter does not match with type java.util.Map<java.lang.Object,java.lang.Object> of variable loadOptions
   - Make classes org.eclipse.emf.ecore.resource.URIConverter and java.util.Map extend a common superclass

   Preondition Violations
   Unmatched statement loadOptions=new HashMap<Object,Object>(); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted
