Michael Osipov commented on MNG-6618:
-------------------------------------
[~slachiewicz], let's merge it and see what happens. I guess it was proven to
work earlier. Karl wants to continue on the release.

> Hi, this is the same issue as
> [MNG-6360|https://issues.apache.org/jira/browse/MNG-6360]. Unfortunately I
> was not able to reopen it so I am creating new one.
> I was able to reproduce it when I tried to create maven plugin for running
> kafka broker during integration tests. Kafka refers to org.slf4j.event.Level
> and this causes following exception during plugin execution.
> {code:java}
> [ERROR] [KafkaServer id=1] Fatal error during KafkaServer shutdown.
