I am able to start up my Ignite server on Java 17 by adding some JVM arguments the ignite.sh script but when I startup my Ignite client via Ignition.start or Ignition.startClient I am getting reflection exceptions.
Is there a way to:
I know these issues could be fixed by using Java 11 but that is not an option.
Below is stack trace I get after calling Ignition.start

Edit, to anyone that finds this I was incorrectly passing in the JVM arguments when starting up my spring boot application. Once I fixed that the InaccessibleObjectException no longer occurred.
Below is the list of arguments I used:
--add-exports=java.base/sun.nio.ch=ALL-UNNAMED
--add-exports=java.management/com.sun.jmx.mbeanserver=ALL-UNNAMED
--add-exports=jdk.internal.jvmstat/sun.jvmstat.monitor=ALL-UNNAMED
--add-exports=java.base/sun.reflect.generics.reflectiveObjects=ALL-UNNAMED
--add-opens jdk.management/com.sun.management.internal=ALL-UNNAMED
--add-opens java.base/java.nio=ALL-UNNAMED
--add-opens java.base/java.util=ALL-UNNAMED
--add-opens java.base/java.lang=ALL-UNNAMED
In the end the problem was that I was not properly passing in the jvm arguments. Once I fixed that the application works with Java 17 given the arguments above. I suppose these are no guarantees I wont hit some other snags.
