   Preondition Violations

   Type org.eclipse.emf.common.util.EList<org.eclipse.emf.ecore.ETypeParameter> of variable eTypeParameters does not match with type org.eclipse.core.resources.ResourceAttributes of variable resourceAttributes
   - Make classes org.eclipse.emf.common.util.EList and org.eclipse.core.resources.ResourceAttributes extend a common superclass

   Preondition Violations
   Unmatched statement eTypeParameters=new EObjectContainmentEList.Resolving<ETypeParameter>(ETypeParameter.class,this,EcorePackage.EOPERATION__ETYPE_PARAMETERS); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted

   Preondition Violations
