/**
* When the JGroups channel is started externally and injected via {@code ChannelLookup},
* there is a small window where incoming messages will be silently discarded:
* between the time the channel is started externally and the time JGroupsTransport attaches the RpcDispatcher.
*
* In replication mode a put operation would wait for a success response from all the members
* of the cluster, and if the RPC was initiated during this time window it would never get a response.
*
* This test checks that the caller doesn't get a (@code TimeoutException} waiting for a response.
