> This failure appears like it's intermittent when the
> ProducerFailureHandlingTest is run as whole because it hides the timing issue
> involved in the testCannotSendToInternalTopic test method. Running only that
> testCannotSendToInternalTopic test method (I did it from IntelliJ IDE)
> consistently reproduces this failure.
> The real issue is that the initialization of the __consumer_offset topic
> (being accessed in the testCannotSendToInternalTopic test method) is time
> consuming because that topic is backed by 50 partitions (default) and it
> takes a while for each of them to be assigned a leader and do other
> initialization. This times out the metadata fetch (3 seconds) being done by
> the producer during a send(), which causes the test method to fail.
> I've a patch to fix that test method which I'll send shortly.
