> Each time JPAQL query is rendered from CriteriaQuery it has new aliases for table aliases. It should be the same for same CriteriaQuery (or CriteriaQueries that builded in the same way) all the times.
> Reason: QueryStructure uses HashSet to store roots.
> Solution: replace HashSet with LinkedHashSet:
> from
> 	private Set<Root<?>> roots = new HashSet<Root<?>>();
> to
> 	private Set<Root<?>> roots = new LinkedHashSet<Root<?>>();
