I am having trouble using Ignite on JDK 9. I have the following minimal testcase:
package no.ovstetun.ignite;
import org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi;
import org.junit.Test;
public class FailingIgniteTest {
@Test
public void failingIgnite() {
TcpDiscoverySpi discoverySpi = new TcpDiscoverySpi();
}
}
This code sample fails with the following stacktrace:

I am trying to migrate my codebase beyond Java 8, and Ignite is now the only dependency holding me back. I have tried adding --add-module to my runner, but I can't seem to find what is needed to make Ignite work with JDK 9.
The same error is with Ignite versions 2.4.0 and 2.5.0.
Any help would be much appreciated!

Try adding the following parameters when launching Java:
--add-exports=java.base/jdk.internal.misc=ALL-UNNAMED
--add-exports=java.base/sun.nio.ch=ALL-UNNAMED
As an alternative to VM arguments, you can specify --add-exports in META-INF/MANIFEST.MF of your library:
Add-Exports: java.base/jdk.internal.misc
