  • I have searched the issues of this repository and believe that this is not a duplicate.

Ⅰ. Issue Description

In idea debug，springcloud-jpa-seata/order-service

@Transactional(rollbackFor = Exception.class)
public void create(String userId, String commodityCode, Integer count)  {

    BigDecimal orderMoney = new BigDecimal(count).multiply(new BigDecimal(5));
    Order order = new Order();
    order.setUserId(userId);
    order.setCommodityCode(commodityCode);
    order.setCount(count);
    order.setMoney(orderMoney);
    orderDAO.save(order);

    /** debug  breakpoint */
    storageFeignClient.deduct(commodityCode, count);
}

"seata-server java.lang.OutOfMemoryError: Direct buffer memory" appears during debugging.
