>                 Key: KAFKA-9356
>                 URL: https://issues.apache.org/jira/browse/KAFKA-9356
>             Project: Kafka
>          Issue Type: Bug
>            Reporter: Roman Leventov
>            Priority: Major
>
> {{InMemoryWindowStore.put()}} and {{InMemorySessionStore.put()}} call {{computeIfAbsent()}} method on {{ConcurrentSkipListMap}} objects which opens up possibility for data loss because {{ConcurrentSkipListMap.computeIfAbsent()}} is not an atomic operation.
> Possible fix: replace {{ConcurrentSkipListMaps with synchronized[Sorted, Navigable]Map(new TreeMap<>())}}.
