@sancar I think this is a similar problem solved with #9443.
Imagine that member is restarted, clients reconnects it when it's available but uses the old proxy so no new proxy is created on member side after reconnection.
WDYT?

@emrahkocaman Yes, you are right. This is exactly why it is not working. Client only creates proxy on server when client.getMap called. Similarly for example PutOperation also does not create proxy. A new joined member gets old proxies via PostJoinOperation.

So this issue only happens when there is single node and it is restarted. And proxy only used from client.
I am not sure what should be the solution. May be all operations coming from client should create the related proxy on the server.

Ok. I remembered why map.put does not create proxy on the server when done from client
Following code prints 1 0 0 both on node and client. I guess we don't want to break this behaviour.

    IMap<Object, Object> a = instance.getMap("a");
    System.out.print(instance.getDistributedObjects().size());
    a.destroy();
    System.out.print(instance.getDistributedObjects().size());
    a.put(1, 1);
    System.out.print(instance.getDistributedObjects().size());
