> SpilledSubpartitionView not protected against concurrent release calls

>                 Key: FLINK-8425
>                 URL: https://issues.apache.org/jira/browse/FLINK-8425
>             Project: Flink
>          Issue Type: Bug
>          Components: Network
>    Affects Versions: 1.1.0, 1.0.1, 1.0.2, 1.0.3, 1.2.0, 1.1.1, 1.1.2, 1.1.3, 
> 1.1.4, 1.3.0, 1.2.1, 1.3.1, 1.4.0, 1.3.2
>            Reporter: Nico Kruber
>            Priority: Minor
>
> It seems like {{SpilledSubpartitionView}} is not protected against 
> concurrently calling {{releaseAllResources}} as the other 
> {{ResultSubpartitionView}} implementations. These may happen due to failures, 
> e.g. network channels breaking, and will probably only result in some 
> unexpected exceptions being thrown, e.g. from reading from a closed file 
> reader.
