Ryan Blue commented on AVRO-1655:
---------------------------------
The next release we could do it in is 1.8.x, since the major version number
follows the data format.
You're right that it would help to do something that we can put in a 1.7.x
release, so I guess we should do both: fix the NPE and add the right
constructor to avoid the problem. Would you mind updating the patch?

> 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.
