An assertion in {{OneToManyPersister#buildTableUpdate}} The problem seems to be too strict or maybe even wrong that we currently don’t handle abstract/denormalized tables in the collection persister. {{assert tableReference.getTableName().equals( elementType.getIdentifierMapping().getContainingTableExpression() )}} I think it should rather be {{assert elementType.containsTableReference(tableReference.getTableName())}} ( https://hibernate.atlassian.net/browse/HHH-16358#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-16358#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!
