Question

Java代码：

Protocol 'Store' can only be used as a generic constraint because it has Self or associated type requirements

JavaScript代码：

import javax.script.Invocable;
import javax.script.ScriptEngine;
import javax.script.ScriptEngineManager;
public class WebCryptoInvoke {
  public static void main(String[] args) throws Exception {
    ScriptEngineManager manager = new ScriptEngineManager();
    ScriptEngine engine = manager.getEngineByName("JavaScript");
    if (!(engine instanceof Invocable)) {
      System.out.println("Invoking methods is not supported.");
      return;
    }
    Invocable inv = (Invocable) engine;
    String scriptPath = "/home/rajasekhar/Desktop/webcrypto.js";

    engine.eval("load('" + scriptPath + "')");
    Object webCrypto = engine.get("webcrypto");
    Object result = inv.invokeMethod(webCrypto, "generateKeyPair");
    System.out.println(result);
  }
}

错误：

线程中的异常＆＃34; main＆＃34; javax.script.ScriptException： ReferenceError：＆＃34; window＆＃34;没有定义 /home/rajasekhar/Desktop/webcrypto.js在第9行 jdk.nashorn.api.scripting.NashornScriptEngine.throwAsScriptException（NashornScriptEngine.java:470）在 jdk.nashorn.api.scripting.NashornScriptEngine.invokeImpl（NashornScriptEngine.java:392）在 jdk.nashorn.api.scripting.NashornScriptEngine.invokeMethod（NashornScriptEngine.java:199）在WebCryptoInvoke.main（WebCryptoInvoke.java:20）引起： /home/rajasekhar/Desktop/webcrypto.js:9 ReferenceError：＆＃34; window＆＃34;是未定义于 jdk.nashorn.internal.runtime.ECMAErrors.error（ECMAErrors.java:57）at at jdk.nashorn.internal.runtime.ECMAErrors.referenceError（ECMAErrors.java:319）在 jdk.nashorn.internal.runtime.ECMAErrors.referenceError（ECMAErrors.java:291）在 jdk.nashorn.internal.objects.Global。的 noSuchProperty （Global.java:1441）在 jdk.nashorn.internal.scripts.Script $重新编译$ 2 $ $ 86 webcrypto.generateKeyPair（/home/rajasekhar/Desktop/webcrypto.js:9）在 jdk.nashorn.internal.runtime.ScriptFunctionData.invoke（ScriptFunctionData.java:637）在 jdk.nashorn.internal.runtime.ScriptFunction.invoke（ScriptFunction.java:494）在 jdk.nashorn.internal.runtime.ScriptRuntime.apply（ScriptRuntime.java:393）在 jdk.nashorn.api.scripting.ScriptObjectMirror.callMember（ScriptObjectMirror.java:199）在 jdk.nashorn.api.scripting.NashornScriptEngine.invokeImpl（NashornScriptEngine.java:386） ......还有2个
