- Snapshot `LeafOperator` execution metadata before merging so we stop hitting `INTERNAL=Caught exception while executing leaf stage: java.util.ConcurrentModificationException`, and emit a clear error log when a leaf stage fails. - Treat null/empty `StageStats` as “no stats” in `MultiStageStatsTreeBuilder`, ensuring the broker’s stage-stats tree shows `EMPTY_MAILBOX_SEND` placeholders instead of recursing into missing stages. - Add broker/runtime regression tests covering mixed empty/populated stage stats and the concurrent metadata merge path (`MultiStageBrokerRequestHandlerTest`, `MultiStageStatsTreeBuilderTest`, and `LeafOperatorTest`). -- This is an automated message from the Apache Git Service.
