--------------------------------------
Summary: MVCC TX: Multiple H2ResultSetIterator closing leads to
assertion in MvccProcessor
Key: IGNITE-9428
URL: https://issues.apache.org/jira/browse/IGNITE-9428
Project: Ignite
Issue Type: Bug
Components: mvcc
Reporter: Roman Kondakov
Reproducer:
{{CacheMvccSqlTxQueriesAbstractTest#testAccountsTxDmlSumSql_WithRemoves_SingleNode}}
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.
