java 11 rmi NoClassDefFoundError(Java 11 RMI NoClassDefFoundError)
本文介绍了Java 11 RMI NoClassDefFoundError的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我更新了我的应用程序以使用Java 11，并且在尝试通过RMI重新绑定对象时收到以下错误。该应用程序在Java 8上运行良好。
他们说NoClassDefFoundError可能是由于类路径中缺少类或静态块中的错误而发生的。
$Proxy0类显然是在运行时创建的类，因此它不应该位于类路径中，但我想知道rmiregristy是否知道这一点。
我没有看到任何可能导致问题的静态代码块。
接受任何建议。

如果我使用推荐答案附带的rmilist可执行文件，则会遇到此问题。但使用代码创建注册表似乎是一个很好的解决办法。
package org.ets.speechrater.util;
import java.rmi.registry.LocateRegistry;
import java.rmi.registry.Registry;
import java.util.concurrent.TimeUnit;
public class RMIregistry {
static ETSLogger logger = ETSLogger.getLogger(RMIregistry.class
.getName());
public static void main(String args[]) {
try {
Registry registry = LocateRegistry.createRegistry(Integer.valueOf(args[0]));
logger.info("Server ready");
while(true) {
TimeUnit.MINUTES.sleep(1000);
}
} catch (Exception e) {
logger.error("Server exception: " + e.toString(),e);
}
}
}
