Hi,
Is there a way to tell if a lazily fetched Collection is already loaded without
accessing the field and forcing it to load?
Yes. [1]
fetching a large collection may be expensive.
Check [2]. May be useful.

I want to add a new
persistent entity to a Collection, but only if the Collection has
already been fetched - because fetching a large collection may be
expensive. But once it has been fetched it must be kept it up to date in
memory.
@OneToMany(mappedBy="listHolder", fetch=FetchType.LAZY,
cascade={CascadeType.PERSIST,CascadeType.REMOVE})
private List<Member> memberList;
