>
> Hello,
> There seems to be a problem with the call to TopologyTestDriver.close() : the
> processors are all closed when it subsequently try to flush the state store's
> record cache.
> The error is :
>
> {code:java}
> org.apache.kafka.streams.errors.ProcessorStateException: topology-test-driver
> Failed to flush state store my-aggregate-store
> at
> org.apache.kafka.streams.processor.internals.ProcessorStateManager.flush(ProcessorStateManager.java:486)
> ....
> Caused by: java.lang.IllegalStateException: The processor is already closed
> at
> org.apache.kafka.streams.processor.internals.ProcessorNode.throwIfClosed(ProcessorNode.java:147)
> ....
> {code}
> Attached are the class and the test class reproducing the problem.
> When I add .withCachingDisabled() on the state store the problem is gone.
