------------------------------------------
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.
