Graal-js 抛出文件系统提供程序错误

问题描述

我正在尝试运行简单的代码 - 添加了本文档中提到的所有依赖项：https://github.com/graalvm/graal-js-jdk11-maven-demo/blob/master/pom.xml

    ScriptEngine graaljsEngine = new ScriptEngineManager().getEngineByName("graal.js");
    try {
        graaljsEngine.eval(SOURCE);
    } catch (ScriptException e) {
        e.printstacktrace();
    }

我仍然看到以下错误：

  org.graalvm.polyglot.polyglotException: java.util.ServiceConfigurationError: 
   java.nio.file.spi.**FileSystemProvider**: Provider 
   org.apache.sshd.client.subsystem.sftp.SftpFileSystemProvider Could not be instantiated

解决方法

解决方案：Bouncy Castle 安全提供程序无法向 JCE 提供程序注册。尝试将 sshd-core 依赖库的版本降级到 JDK11 的 1.2
