HashSet删除错误

Question

您好，我试图从HashSet中删除一个具有由我创建的称为“ Product”的实体的元素，这是代码：

Set listaItemsTrans = this.getTransaction().getTransactionItems();
        HashSet listaIteratorI = new HashSet();

        listaIteratorI.addAll(listaItemsTrans);

        Iterator itemSet = listaIteratorI.iterator();

        while (itemSet.hasNext())
        {
            Product prodBif = (Product) itemSet.next();
            logger.debug("Prod bif = " + prodBif.getIdProduct() + " = " + "Prod search = " + prodSearch.getIdProduct());
            if (prodBif.getIdProduct().compareTo(prodSearch.getIdProduct()) == 0)
            {
                logger.debug("El Producto ha sido encontrado");
                try
                {
                    logger.debug("ProdBif " + prodBif);
                    logger.debug("Lista de productos 3 " + this.getTransaction().getTransactionItems());
                    boolean isRemoved;
                    isRemoved = this.getTransaction().getTransactionItems().remove(prodBif);
                    logger.debug("isRemoved? " + isRemoved);
                }
                catch (Exception e)
                {
                    e.printStackTrace();
                }

                logger.debug("Lista de productos 4" + this.getTransaction().getTransactionItems());
                prodBif = prodSearch;
                this.getTransaction().getTransactionItems().add(prodBif);
                logger.debug("Lista de productos 5" + this.getTransaction().getTransactionItems());
                isOkey = true;
            }
        }

产品是相同的，我已经检查过，但是我要把产品相等：

我不知道为什么会这样，我想念的东西吗？

注意1：，当我尝试使用具有代码功能的其他产品做相同的事情

注意2：我受硬件限制使用Java 1.4
