>
> The test (and {{NumOwnersNodeStopInSequenceTest}} as well) uses {{StateSequencerUtil.advanceOnInboundRpc()}}, which replaces the {{PerCacheInboundInvocationHandler}} and rewires all the components.
> The problem is that rewiring {{StateConsumerImpl}} causes it to create a new {{SemaphoreCompletionService}}, but there's no synchronization when reading the field, a "background" task could finish on another thread and release the permit on the old {{SemaphoreCompletionService}} instance.
