我尝试用Java 9运行我的应用程序（前端用Java Swing开发，服务器用部署在Wildfly 8上的EJB开发）。当客户端尝试建立EJB连接时，出现以下异常：

我看到Java 9中引入的新模块管理存在一些问题，但我不明白应该怎么做。

根据this answer，您需要将--add-opens java.base/java.io=ALL-UNNAMED添加到启动应用程序的java命令中。

添加以下JVM参数：

--add-exports=java.base/sun.nio.ch=ALL-UNNAMED
--add-opens=java.base/java.lang=ALL-UNNAMED
--add-opens=java.base/java.lang.reflect=ALL-UNNAMED
--add-opens=java.base/java.io=ALL-UNNAMED
--add-exports=jdk.unsupported/sun.misc=ALL-UNNAMED

不再达到上述异常，之前失败，但出现以下异常：

java.lang.ClassNotFoundException: com.dataloy.client.Main
    at jdk.deploy@9-ea/com.sun.deploy.security.DeployURLClassLoader.findClass(Unknown Source)
    at jdk.javaws@9-ea/com.sun.jnlp.JNLPClassLoader.findClass(Unknown Source)
    at java.base/java.lang.ClassLoader.loadClass(Unknown Source)
    at jdk.javaws@9-ea/com.sun.jnlp.JNLPClassLoader.loadClass(Unknown Source)
    at java.base/java.lang.ClassLoader.loadClass(Unknown Source)
    at jdk.javaws@9-ea/com.sun.javaws.Launcher.doLaunchApp(Unknown Source)
    at jdk.javaws@9-ea/com.sun.javaws.Launcher.run(Unknown Source)
    at java.base/java.lang.Thread.run(Unknown Source)

我需要使更多的模块可见，但我很难理解是哪一个。
