Not so fast. You changed order of persist which are very important in this case. Ok I accpet your changes in model but try the folowwing order...I changed order of the begining ..of course order_inserts=false and works fine....

 SaleDocumentItem saleDocumentItem = new SaleDocumentItem();
		session.persist(saleDocumentItem);

		SaleDocumentSummary saleDocumentsummary = new SaleDocumentSummary();
		session.persist(saleDocumentsummary);

		saleDocumentsummary.addItem(saleDocumentItem);

		Product product = new Product();
		session.persist(product);
		saleDocumentItem.setProduct(product);

		SaleDocument saleDocument = new SaleDocument();
		session.persist(saleDocument);
		saleDocument.addItem(saleDocumentItem);

		SaleDocument correction = new SaleDocument();
		session.persist(correction);

		saleDocument.setCorerctionSubject(correction);
