Jose Armando Garcia Sancio commented on KAFKA-7565:
---------------------------------------------------
The Github PR 6427 was merge to trunk. The next version of Kafka should replace
the null pointer exception with an illegal state exception with more
information what should help us debug the issue if it happens again.
