>                 URL: https://issues.apache.org/jira/browse/IGNITE-10473
>             Project: Ignite
>          Issue Type: Bug
>          Components: mvcc
>            Reporter: Andrey Mashenkov
>            Priority: Major
>              Labels: transactions
>
> IgniteCacheSystemTransactionsSelfTest.testSystemTxInsideUserTx fails in Mvcc mode due to  inner system-tx commits external mvcc-tx unexpectedly.
> We have to analyse cases where system tx can be used and deprecated such cases.
> Then we have to either add MVCC support for system caches somehow or allow non-mvcc nested tx.
