heaven commented on IBATIS-334:
-------------------------------

I cannot get the trace detail from my work enviorment. But I ensure this is something not normal.
The nullpointexception is from GeneralStatement.java 188 (2.2.0).
And I use spring framework to manage my jdbc transaction. 
And I just call a queryForList method and the queryForList has a relation with another sqlmap's query.so in a thread there are to query ,one by me,one by ibatis self.
I trace the code ,the first time ibatis can get my transaction manager , but the second time ibatis cannot get the tans ,so the boolean autoStart be true,and the trans is null ,a nullpointexception throws .

when I change back to 2.1.7 ,it works.
