Georg Tsakumagos commented on CSV-93:
-------------------------------------
I think it is not a problem because the attached patch activate this behavior
only if the *new* CSVFormat option *WithNullObjectPatternEnabled* is set.
The handling of null values is a special treatment which must be activated.
It is not activated by default.
Please review the patch and judge it again.
