Thanks @iverase. I missed the fact that modification could happen before the synchronized call.
We don't want to take concurrent modifications into account since we need to report the shards that are part of the current partial reduce. I opened #49829 to use a different array that is synchronously accessed and modified. This should fix the concurrent issue and the wrong reporting.

I see, then I close this PR in favour of #49829 |

Currently we use the list generated by the AtomicArray in ArraySearchPhaseResults but this List is shared between threads and can get nullify. This change collects results in a local list to prevent concurrent issues.
