create index on unidirectional OneToMany

Is it possible to create an index on a unidirectional OneToMany relation? There is no column on the related entity to put @Index on. I tried @KeyIndex and @ElementIndex but they don't work either.

e.g.

My use case (simplified)

@Entity
class Order {
    @OneToMany
    @JoinColumn
    List<OrderLine> orderlines;

OrderLine has no reference to Order.
