> In AvroFileFormatFactory#RowDataAvroWriterFactory a lambda function is used
> to create the factory. This can causes
> {code:java}
> Caused by: java.lang.IllegalArgumentException: Invalid lambda
> deserialization{code}
> There's other similar issues like FLINK-20147, FLINK-18857 and FLINK-18006
> and the solution so far seems to have been to replace the lambda with an
> anonymous class instead.
