…tions causing eager initialization In hbm.xml, fetch="join" and lazy="true" are independent — the collection stays lazy and uses join fetching only when initialized. In orm.xml, fetch-mode="JOIN" maps to @fetch(FetchMode.JOIN) which forces eager loading. Since a lazy collection uses a separate SELECT regardless of fetch style, dropping fetch-mode="JOIN" preserves the same runtime behavior.
