   Preondition Violations

   Type org.eclipse.emf.ecore.impl.BasicEObjectImpl.EPropertiesHolder of variable eProperties does not match with type java.lang.StringBuffer of variable buffer
   - Make classes org.eclipse.emf.ecore.impl.BasicEObjectImpl.EPropertiesHolder and java.lang.StringBuffer extend a common superclass

   Preondition Violations
   Unmatched statement eProperties=new EPropertiesHolderImpl(); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted

   15 | buffer = new StringBuffer(value);

   Preondition Violations
   Unmatched statement buffer=new StringBuffer(value); cannot be moved before or after the extracted code, because it has dependencies to/from statements that will be extracted
