Stephan Ewen commented on FLINK-4759:
-------------------------------------
I think that should not be changed. The `DataOutputViewStream` holds no
resources, no need to close.
The underlying stream should not be closed in that method, because it is just
passed into that method, there is no guarantee that no one else will want to
use it.
