> Somehow the producer thread for the transport-thread iteration is blocked, but without waiting for the persistence mutex. Maybe it's waiting for a topology? Not sure if it's relevant, but the last test to run was {{testClearWithFlag}}, so the data container was empty and the store had 5 entries.

> This scenario happens unintentionally in {{RebalancePolicyJmxTest}}, because the test waits for the default cache to finish rebalancing before killing the coordinator but doesn't care about the {{CONFIG}} cache:
> * A and B are running, rebalancing is disabled, then C and D join
> * Re-enable rebalance, but stop B and A before the rebalance is done
> * C sees the finished rebalance, D sees the READ_OLD phase
> * C becomes coordinator and should recover with C's topology, but instead has an assertion failure and doesn't install a stable topology

> `application/x-java-object` needs to have the application classes deployed on the server in order to do anything useful with it, and the server must also be able to do reflection on those application classes.
> We should steer users towards always using `application/x-protostream` instead, because the protobuf schemas are much easier to deploy to the server. The first step would be to make protostream the default marshalling mechanism in the client.
