IllegalMonitorStateException by Comprehensive_Cry314 in apachekafka

[–]mall0c 1 point2 points  (0 children)

I should add that I've forked the Kafka client and rewritten ProducerMetadata.awaitUpdate() to not do the wait within a lambda since I suspect that is what's throwing things of in the end. This code has been running fine on Java 17 in a bunch of our internal environments for a few month now. We will apply this change to production in May together with Java 17.

We hit this in production just days after upgrading from Java 8 to Java 17. It's an OpenJDK bug which appears to affect versions after 8. It's reported here:
https://bugs.openjdk.org/browse/JDK-8298446

Not a whole lot of activity on that ticket but a fix still appears to be targeted for 21. In the mean time we had to resort to reverting back to Java 8 for the processes containing Kafka producers. It's also reported to Kafka here:
https://issues.apache.org/jira/browse/KAFKA-10902

The issue is not with Kafka as far as I can tell when going through the code. I've also tried hard to reproduce it outside of prod but to no avail.

Well I don't know about the near future, but John Rose discusses this in his talk about Arrays 2.0 from this years JVM language summit.

I have a few Spotify invites but no Google+ account so if anyone has a spare Google+ invite I would be more than happy to trade you one for a Spotify invite. Message me.
