Aljoscha Krettek commented on FLINK-17862:
------------------------------------------
How is it leaked in the operator?
In general, the fact that the operators are visible/usable in the
{{DataStream}} API was a mistake. We should fix that at some point but it's not
easy task.

> The {{StreamingRuntimeContext}} is annotated with {{Internal}}. However, user
> could get it in {{AbstractUdfStreamOperator}}. Then, many internal classes,
> e.g. {{TaskManagerRuntimeInfo}}, will be leaked from it.
