for(Root<?> root : this.criteriaQuery.getRoots()) {
String rootClassName = root.getJavaType().getName();
EntityEntry rootEntityEntry = EntityAnalyzer.getInitialEntityEntry(rootClassName);
Objectref rootObjectref = getObjectrefByEntityEntry(rootClassName, rootEntityEntry);
createdObjectEntityMap.put(rootClassName, rootObjectref);
newVDB.addRequired(rootObjectref.getObjectId(), rootEntityEntry);
