Empty Integer field is parsed as 0

[mayankanand7]

I have a Integer column in an excel sheet. Case 1 : If the column is not present in the sheet, then the value of the column returned by poi-object-mapper for each row is null. It is expected behaviour. Case 2 : If the column is present in the sheet and some rows have value missing for the column, then the poi-object-mapper returns 0 for missing value. The expected behaviour is to return null for the missing values.
