    Status: Patch Available  (was: Open)

>                 Key: AVRO-1655
>                 URL: https://issues.apache.org/jira/browse/AVRO-1655
>             Project: Avro
>          Issue Type: Bug
>    Affects Versions: 1.7.7
>            Reporter: Lars Francke
>            Assignee: Lars Francke
>         Attachments: AVRO-1655.1.patch
>
>
> The code just does
> {code}
>       for (Field f : fields) {
> {code}
> without ever checking if fields is set. There is a {{createRecord}} version that does
not take fields so this can be empty. This is especially annoying within the Scala/Spark REPL
as that immediately prints out the result of everything you type so it calls {{toString}}
which then fails and that even leaves the object unset in the REPL.
> I'll attach a patch that checks whether {{fields}} is null.
