> In the thread, Spark ClosureCleaner or java serializer OOM when trying to grow, Jay Luan reported that ClosureCleaner#ensureSerializable() resulted in OOME.
> The cause was that ObjectOutputStream keeps a strong reference of every object that was written to it.
> This issue tries to avoid OOME by calling reset() more often.
