Paolo Patierno commented on KAFKA-5481:
---------------------------------------
[~ijuma] I got your point using a log tracing in the following way :
{code}
log.trace("Received ListOffsetResponse {} from broker {}",
lor.toString(response.requestHeader().apiVersion()), node);
{code}
It seems to me not so natural because most of the times we don't call toString
explicitly in the code.
> ListOffsetResponse isn't logged in the right way with trace level enabled

> Hi,
> when trace level is enabled, the ListOffsetResponse isn't logged well but
> just the class name is showed in the log :
> {code}
> [2017-06-20 14:18:50,724] TRACE Received ListOffsetResponse
> org.apache.kafka.common.requests.ListOffsetResponse@7ed5ecd9 from broker
> new-host:9092 (id: 0 rack: null)
> (org.apache.kafka.clients.consumer.internals.Fetcher:674)
> {code}
> The class doesn't provide a toString() for such a thing.
