I developed couple of entity classes as attached(StockTransferOutCarton.java, StockTransferOutTask.java, StockTransferOutItem.java).
When I start the application, the JPA create the tables automatically(stock_transfer_out_carton, stock_transfer_out_task, stock_transfer_out_item), however, the table, stock_transfer_out_carton creates a strange foreign key, stock_transfer_out_carton_id, which is not mentioned in StockTransferOutCarton.java entity class). The generated creation script for table, stock_transfer_out_carton is shown as below. Please see the following script especially the line in red.
mysql> show create table stock_transfer_out_carton;

Why it generated the two strange lines?
