Benedict commented on CASSANDRA-7795:
-------------------------------------
LGTM, +1
Might want to have a quick look at StreamTask.prepare(), which calls
.maybeCompleted() without holding the object monitor. which may be a very very
unlikely race condition.

>
> StreamReceiveTask is not thread safe when stream session is aborted and
> completion task is running.
> Also, StreamReceiveTask keeps references to SSTableWriter until completion
> task runs and session completes. Currently, StreamReceiveTask's completion
> task runs on StorageService's NonPeriodicTask and it may take longer to
> execute.
> Patch attached to fix above.
