>
> 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.
