我在 JDK 9 上使用 Ignite 时遇到问题。我有以下最小测试用例：
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();
}
}
此代码示例失败并显示以下堆栈跟踪：

我正在尝试将我的代码库迁移到 Java 8 之外，而 Ignite 现在是唯一阻碍我的依赖项。我尝试过添加--add-module给我的跑步者，但我似乎找不到让 Ignite 与 JDK 9 一起工作所需的东西。
Ignite 版本 2.4.0 和 2.5.0 也出现同样的错误。
任何帮助将非常感激！
尝试在启动 Java 时添加以下参数：
--add-exports=java.base/jdk.internal.misc=ALL-UNNAMED
--add-exports=java.base/sun.nio.ch=ALL-UNNAMED
