Commit 1674398 from [[email protected]] in branch 'avro/trunk'
[ https://svn.apache.org/r1674398 ]
AVRO-1655. Java: Fix NPE in RecordSchema#toString. Contributed by Lars Francke.
This also adds a variant of Schema.createRecord with a field list to
allow callers to create valid record schemas in a single call.
> RecordSchema#fieldsToJson can throw NullPointerException

> 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, AVRO-1655.2.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.
