JDK11环境下，base可以获取Nashorn脚本对象，在biz获取不到

[langke93]

Feature description

使用以下代码分别运行在base和biz

        // 创建 ScriptEngineManager
        ScriptEngineManager manager = new ScriptEngineManager();
        // 列出所有可用的 ScriptEngineFactory
        List<ScriptEngineFactory> factories = manager.getEngineFactories();
        for (ScriptEngineFactory factory : factories) {
            logger.info("Engine: " + factory.getEngineName());
            logger.info("Language: " + factory.getLanguageName());
            logger.info("Mime Types: " + factory.getMimeTypes());
            logger.info("------");
        }
        // 获取 JavaScript 引擎
        ScriptEngine engine = manager.getEngineByName("JavaScript");

        if (engine == null) {
            logger.info("JavaScript 引擎不可用！");
        }else{
            logger.info("engineName: " + engine.getFactory().getEngineName());
        }

在base下执行，可以获取到，在biz下就获取不到
通过调试发现在BizClassLoader的jdkClassLoader.parent.classLoaderValueMap 有加载nashorn模块，但是代码获取不到该对象
