   Preondition Violations

   Type org.eclipse.emf.edit.provider.Disposable of variable wrappers does not match with type org.eclipse.core.resources.ResourceAttributes of variable resourceAttributes
   - Make classes org.eclipse.emf.edit.provider.Disposable and org.eclipse.core.resources.ResourceAttributes extend a common superclass

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

   16 | resourceAttributes = resource.getResourceAttributes();

   Preondition Violations
   Unmatched statement resourceAttributes=resource.getResourceAttributes(); cannot be moved before or after the extracted code, because it has dependencies to/from statements that will be extracted

   Precondition Violations (4)
   Row | Violation
   --- | ---
   1 | Type org.eclipse.emf.edit.provider.Disposable of variable wrappers does not match with type org.eclipse.core.resources.ResourceAttributes of variable resourceAttributes
   2 | Unmatched statement wrappers=new Disposable(); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted
   3 | Unmatched statement resourceAttributes=resource.getResourceAttributes(); cannot be moved before or after the extracted code, because it has dependencies to/from statements that will be extracted
   4 | The refactoring of the clones is infeasible, because the number of macthed statements is equal to zero
