Vyacheslav Daradur resolved IGNITE-9742.
----------------------------------------
Resolution: Won't Fix
Closed "won't fix" because nullifying the field is an explicit action that was
taken to reduce memory consumption on server nodes.

> Key: IGNITE-9742
> URL: https://issues.apache.org/jira/browse/IGNITE-9742
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 2.6
> Reporter: Vyacheslav Daradur
> Assignee: Vyacheslav Daradur
> Priority: Major
> Labels: discovery
>
> The following code is called in {{GridDhtPartitionsExchangeFuture#onDone}}:
> {code}
> ((DiscoveryCustomEvent)firstDiscoEvt).customMessage(null);
> {code}
> That means a global instance of 'DiscoveryCustomEvent' is being
> mutated outside discovery-spi infrastructure. It also means that
> discovery listeners receive 'DiscoveryCustomEvent' with 'null' field
> instead of 'CustomMessage' which they may rely on.
