wish helps you If you are using the default flush mode (AUTO) and if you are executing your query within a transaction, the JPA specification guarantees that a Query will not return stale or incorrect data:

code :
public enum FlushModeType {
    COMMIT,
    AUTO
}

I wish this helpful for you Your query is fine, but it doesn't return what you want. It returns all the menus containing at least one allowed operation. And since it returns Menus, and menus have operations, the returned menus contain all their operations. Because that's what a association is: it doesn't contain entries specific to a given query. It contains the operations of the menu.
What you need, instead of returning the menus, is to return the allowed operations. You can then get their menu using the ManyToOne association:
code :
select o from Operation o
join o.allowedRoles role
where role role in :roles
