I have some entities with@ManyToMany relation:

@ManyToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER)
@JoinTable(name = "buses_drivers",
        joinColumns = @JoinColumn (name = "driver_id_inner", referencedColumnName = "driver_id"),
        inverseJoinColumns = @JoinColumn (name = "bus_id_inner", referencedColumnName = "bus_id"))
private List<Bus> buses;

and

@ManyToMany(mappedBy = "buses", fetch = FetchType.EAGER, cascade = CascadeType.ALL)
private List<Driver> drivers;

When execute saving Driver model with some Bus models, all ok. Tables buses_drivers store all keys those entities. But when saving Bus model with drivers, table doesn't change. I think problem with inverseJoinColmns mapping.

For people doesn't understand from the accepted answer. This is more appropriate : Java: saving entities with ManyToMany association

I came across with this problem in test cases when filling test data.

When there is an owning side you just can save child just with owner.
