work)
> Network serialization of arrays of NetworkMessage objects doesn't work
> ----------------------------------------------------------------------
>
> Key: IGNITE-18589
> URL: https://issues.apache.org/jira/browse/IGNITE-18589
> Project: Ignite
> Issue Type: Bug
> Reporter: Aleksandr Polovtcev
> Assignee: Roman Puchkovskiy
> Priority: Major
> Labels: ignite-3
>
> Consider the following class hierarchy:
> {code:java}
> @Transferable
> interface A extends NetworkMessage {}
> @Transferable
> interface B extends NetworkMessage {
> A[] arrayField();
> }
> {code}
> When sending a message of type {{B}} from one node to another, the following
> exception occurs:
> {{java.lang.IllegalStateException: Cannot merge descriptors in the correct
> order; a cycle?}}
> This happens, because a descriptor of type {{A}} can't be found on the
> receiving node.
> This problem also appears if we change {{B}}'s field to {{Collection<A>}},
> but provide {{Arrays.asList(new AImpl())}}, because the wrapper contains an
> array inside.
