> In a use case that has 2 persistence classes - parent and child. Parent and
> child is one-many relationship.
> Parent entity has a collection of children.
> When order-by is set for collection of children and data cache is enabled,
> inserting children, updating children's field value that is used by ordering
> will cause collection out of order. But data cache doesn't aware this and
> returned out of order collection.
> If data cache is disabled, it always use SQL query with "ORDER BY" applied so
> collection is returned in correct order.
> Test case will be attached.
