Ah, so if I'm following you, making the `ThreadLocal<KafkaProducer>` into
`ThreadLocal<KafkaProducer<String, String>>` would solve the issue, correct?
I'd prefer to not change to`SendToKafka<K, V>` because it implies that we might
be sending something other than String in this implementation. We would not
because the message generator sends Strings and I'd prefer to not generalize
that.
