--------------------------------------
Greetings,
I can also report Ignite server (2.14, 2.15) working with Java17 - on top of
RHEL8.5 in my case.
However, I've experienced similar exception when starting Ignite Kafka
connector within Kafka Connect. Connector is instantiated, but later
connector's task fails to start because of
Caused by: java.lang.NoClassDefFoundError: Could not initialize class
org.apache.ignite.internal.util.IgniteUtils
