> 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.
