> The {{put}} method is strongly discourage to be used on {{Properties}} as a
> bad practice, since it allows putting non-string values.
> This has already caused a bug, where a long was put into the properties,
> while Kafka was expecting an integer:
> {code}
> org.apache.kafka.common.config.ConfigException: Invalid value 100000 for
> configuration transaction.timeout.ms: Expected value to be a 32-bit integer,
> but it was a java.lang.Long
