>    Affects Versions: 0.13.0
>         Environment: Ubuntu, LXC, jdk6-x86_64

> When processing multiple splits on the same operator pipeline, the output collector in Operator has a held reference, which causes issues.
> Operator::close() does not de-reference the OutputCollector object Operator::out held by the object.
> This means that trying to allocate space for a new OutputCollector causes an OOM because the old one is still reachable.
