Auto的fulshMode，为什么查询前不自动清理缓存呢？

Question

如下代码，flushMode是auto，为什么在执行query.lst() 的select时没有先自动执行user1入库的insert语句。
按照auto的FulshMode，应该在查询前，flush时，、commit时进行缓存清理的啊。

[code="java"]System.out.println("flushMode="+session.getFlushMode());
//Transaction tx=session.beginTransaction();

        User user1=new User();
        user1.setUserID(13000000);
        user1.setUserName("wa1");
        session.save(user1);



        Query query = session.createQuery("from query.common.User");
        List lst=query.list();

[/code]

When operating outside a transaction, FlushMode.AUTO is a bad thing.
Two options here:
1) no-op the autoFlush processing when outside a transaction
2) explicitly manage the Session's FlushMode setting when outside a transaction
#1 seems more viable, since Session.setFlushMode() might cause problems (or at least extra complexity) with #2
