>          Components: Client - JDBC
>         Environment: I found this problem when calling the driver's wasNull() method on a field that represented a nested JSON object (one level below the root object), using the 'dfs' storage plugin and pointing at my local filesystem.

> GenericAccessor throws an UnsupportedOperationException when isNull() is called. However for other methods it delegates to its ValueVector's accessor. I think it should do the same for isNull().
