Josep Prat commented on KAFKA-13010:
------------------------------------
If this is the reason why we are seeing this bug, by replacing line 60 in
ThreadMetadataImpl the following might cause the test to not fail:
{code:java}
this.producerClientIds = producerClientIds;
{code}
As I can't reproduce the test locally would you be able to try this?
