-------------------------------------------
[~Pavlukhin], could you please do a review?
> JdbcThinClient and Server compatibility broken
> ----------------------------------------------
>
> Key: IGNITE-12369
> URL: https://issues.apache.org/jira/browse/IGNITE-12369
> Project: Ignite
> Issue Type: Bug
> Components: sql
> Reporter: Konstantin Orlov
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Query cancellation support was introduced in IGNITE-5439. From this time
> server expects that ALL request have id. It breaks compatibility with clients
> whose version prior to 2.8.0.
> Furthermore backport of this feature to 8.7 breaks compatibility newer build
> of server with older build of client.
> See {{ClientListenerProcessor#makeFilters}}. New filter with overrided
> _onMessageReceived_ is created here. It tries to read request id and if there
> is not enough data to read long value, it crashes.
