> The fetch task is created during query compilation with the config of the 
> driver. That config will have the valid txn list set. Thus the fetch task 
> will have valid txn list set while doing fetch for ACID tables. But when user 
> does a refetch with cusrsor set to first position it reinitializes the fetch 
> task with the driver config (cached in task config). But by that time, the 
> select query would have cleaned up the valid txn list from the config and the 
> fetch will happen with valid txn list as null. This will cause illegal 
> argument exception.
