----------------------------------
Resolution: Won't Fix
The FLIP mentioned is not yet approved by the community. In addition, the changes introduced by this change are a lot more and have the potential to break user code, if they are not done in conjunction with the other changes that FLIP-21 will (potentially) introduce.

> StreamTask support efficient object reuse. The purpose behind this is to reduce pressure on the garbage collector.
> All objects are reused, without backup copies. The operators and UDFs must be careful to not keep any objects as state or not to modify the objects.
> *FYI, now this thread is blocked by FLIP-21. The pull request attached is closed for a needed rework.*
