Chesnay Schepler commented on FLINK-15773:
------------------------------------------
Shouldn't matter what {{DateTimeZone}} or parent classes defines; the
serialization fails on the inner static {{OfYear}} class which is independent.
> ClosureCleaner fails with joda DateTimeZone

> Key: FLINK-15773
> URL: https://issues.apache.org/jira/browse/FLINK-15773
> Project: Flink
> Issue Type: Bug
> Components: API / Core
> Affects Versions: 1.9.1
> Reporter: Jozef Vilcek
> Priority: Minor
>
> Flink fails to launch my Apache Beam job which uses windowing function with
> time zone. Closure cleaner reports time zone as not serializable. Part of
> stack trace:
>
> {noformat}
> org.joda.time.tz.DateTimeZoneBuilder$OfYear@3b035d0c is not serializable. The
> object probably contains or references non serializable fields.

> Actual instance of DateTimeZone is
> [PrecalculatedZone|https://github.com/JodaOrg/joda-time/blob/v2.10.5/src/main/java/org/joda/time/tz/DateTimeZoneBuilder.java#L1373]
> which itself is serializable but it's fields are not necessarily standalone
> java serializable, because enclosing class it managing their serialization
> and deserialization.
