Hibernate查询返回意外的子列表结果

我有一个HQL查询，如下所示，它返回一个java.util.RandomAccessSubList顺序。子列表的偏移量为1，因此无法访问查询结果列表的第一个元素

SELECT vendor.order FROM OrderVendor vendor WHERE vendor.user.id=? ORDER BY vendor.order.creationTime desc

select order1_.order_id as order1_18_,(..... other fields....) 
from ORDER_VENDOR ordervendo0_ 
inner join ORDER order1_ on ordervendo0_.order_id=order1_.order_id, 
where ordervendo0_.user_id=? 
order by order1_.creationTime desc

我尝试了另一种方法。首先获取OrderVendor的列表，然后使用OrderVendor.getOrder（）方法访问订单。但是这有点麻烦

FROM OrderVendor vendor WHERE vendor.user.id=? ORDER BY vendor.order.creationTime desc

select ordervendo0_.vendor_id as vendor1_20_ (....other fields...) 
from ORDER_VENDOR ordervendo0_, 
ORDER order2_ 
where ordervendo0_.order_id=order2_.order_id 
and ordervendo0_.user_id=? 
order by order2_.creationTime desc limit ?

我的问题是为什么第一个查询返回一个子列表，为什么子列表的偏移量是1

谢谢
