-------------------------
Labels: needsTriage (was: )
> Fix concurrency issue in RedisSet during GII
> --------------------------------------------
>
> Key: GEODE-9899
> URL: https://issues.apache.org/jira/browse/GEODE-9899
> Project: Geode
> Issue Type: Bug
> Components: redis
> Reporter: Jens Deppe
> Assignee: Jens Deppe
> Priority: Major
> Labels: needsTriage
>
> For the most part, access to Radish structures is performed through redis
> commands and thus concurrent access is protected through the
> {{{}StripedCoordinator{}}}. However access outside this protection can occur
> directly through Geode internal flows. In particular, a GII process will
> access the data structures via the {{toData}} and {{fromData}} calls.
> Exceptions can occur if the structure is being modified and, at the same time
> being read. For Example:
> {noformat}
> java.util.concurrent.ExecutionException: java.lang.NullPointerException at
> java.util.concurrent.FutureTask.report(FutureTask.java:122)
