>             Project: Commons DbUtils
>          Issue Type: Improvement
>    Affects Versions: 1.1
>         Environment: JDK 5.0, MSSQL 2000

> While I use dbutil1.1, I got a big different implementation betweeb 1.0 and 1.1.
> Given a Java object, it has a property with Long data type; mapping to database, its table field datatype is bigint.
> If it has a record and its value is null.
> In 1.0 implementation, if I load entity, then we can see the property in Java object is also null.
> But in 1.1 implementation, the Java object will got a Long object with 0 inside.
> This behavior change does big impact if I upgrade from 1.0 to 1.1. It might make application logic fail because origional null status now become a Long(0) value to map to null value in database.
> I suggest to change it back. If null value in database, then mapped Java object should be null as well, not new a Long(0) to be a initial value.
