Java 21 support for confluent schema registry

[kaushiksrinivas]

Does confluent schema registry support java 21 runtime. Is there a documentation link capturing supported java versions for schema registry ?

The whole Confluent Platform adheres to Java versions listed here
https://docs.confluent.io/platform/current/installation/versions-interoperability.html#java

hi @OneCricketeer , thank you for your response.
Apache Kafka supports Java 21 with https://issues.apache.org/jira/browse/KAFKA-15485
Is there any particular reason we don't list Java 21 support for Kafka in the confluent documentation

Every component of the Platform needs to support Java 21, not just Kafka. This includes Schema Registry, REST Proxy, Replicator, Control Center, etc

Hi @OneCricketeer
Can we conclude that components like Schema registry does not support java 21 and hence the whole platform is not listing java 21 ?

@kaushiksrinivas Hello. Yes, that's what the documentation implies.

Have you tried running it, though? Are you experiencing any errors? It's compiled with Java 8
