Reset ObjectOutputStream to prevent OOME
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 PR tries to avoid OOME by calling reset().
