> ---------------------------------------------------------------------------------
>
> Key: IGNITE-9428
> URL: https://issues.apache.org/jira/browse/IGNITE-9428
> Project: Ignite
> Issue Type: Bug
> Components: mvcc, sql
> Reporter: Roman Kondakov
> Assignee: Andrew Mashenkov
> Priority: Major
>
> Due to [IGNITE-9256|https://issues.apache.org/jira/browse/IGNITE-9256] patch, multiple {{H2ResultSetIterator#onClose}} invocation becomes possible. This can be considered as a {{Closable}} contract violation and should be fixed.
> Also this case revealed a bug in {{MvccQueryTrackerImpl}} when multiple {{onDone()}} call leads to multiple query finished acks sent back to the {{MvccCoordinator}} which leads to the problems with the query tracking and assertion errors.
> Reproducer: {{CacheMvccSqlTxQueriesAbstractTest#testAccountsTxDmlSumSql_WithRemoves_SingleNode}}
