Aleksandr Polovtcev updated IGNITE-18589:
-----------------------------------------
Description:
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 type to {{Collection<A>}},
but provide {{Arrays.asList(new AImpl())}}, because the wrapper contains an
array inside.
