The two nodes have the same subscriber. The only difference is the order of starting node. The first started node, we call it as Node1, the second started node is Node2. The Node1 send a message, the Node2 will handle it as expected in remoteListen(@Nullable Object topic, IgniteBiPredicate<UUID, ?> p) But the Node2 send a message, the Node1 can receive it, but never execute the IgniteBiPredicate of remoteListen. You could check the screenshots, it prove the Node1receive the message, but didn't handle it.
