[jira] [Created] (IGNITE-9742) Illegal change of DiscoveryCustomEvent in GridDhtPartitionsExchangeFuture#onDone

Vyacheslav Daradur created IGNITE-9742:
------------------------------------------

             Summary: Illegal change of DiscoveryCustomEvent in GridDhtPartitionsExchangeFuture#onDone
                 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
             Fix For: 2.8


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.
