Subselect fetching does not work when MultiIdentifierLoadAccess is used in Hibernate

Solution Verified - Updated -

Issue

  • Entities are loaded via MultiIdentifierLoadAccess.multiLoad() in one batch via a query using an IN clause.
  • The entities have lazy-fetched OneToMany associations annotated with FetchMode.SUBSELECT.
  • When accessing the associations, they are fetched using one query per parent entity.
