> Using {{disableLogging()}} for either of the built-in state store types causes an initialization loop in the StreamThread.
> Case A - this works just fine:
> {code}
> final StateStoreSupplier testStore = Stores.create(topic)
> .withStringKeys()
> .withStringValues()
> .inMemory()
> // .disableLogging()
> .maxEntries(10)
> .build();
> {code}
> Case B - this does not:
> {code}
> final StateStoreSupplier testStore = Stores.create(topic)
> .withStringKeys()
> .withStringValues()
> .inMemory()
> .disableLogging()
> .maxEntries(10)
> .build();
> {code}
> A brief debugging dive shows that in Case B, {{AssignedTasks.allTasksRunning()}} never returns true, because of a remnant entry in {{AssignedTasks#restoring}} that never gets properly restored.
> See [^App.java] for a working test (requires ZK + Kafka ensemble, and at least one keyed message produced to the "test" topic)
