Rhino中的类型错误:从Java6迁移到Java7。-TypeErrorinRhino:migrationfromJava6toJava7

My project perfectly works on Java 6 (different updates and OS). It uses Rhino as script engine. Now we need to migrate to Java 7 and I found one issue that prevent us to do it. We have code like this:

我的项目非常适合于Java 6(不同的更新和操作系统)。它使用Rhino作为脚本引擎。现在我们需要迁移到Java 7，我发现了一个阻止我们去做的问题。我们有这样的代码:

Context.enter();
try {
    ScriptEngine js = new ScriptEngineManager().getEngineByName("js");
    final ScriptContext cOntext= new SimpleScriptContext();
    context.setAttribute("console", new Object() {
        public void log(String out) {
            logger.info(out);
        }
    }, ScriptContext.ENGINE_SCOPE);
    js.setContext(context);
    js.eval("console.log('test')");
} catch (ScriptException e) {
    logger.error(e);
    e.printStackTrace();
} finally {
    Context.exit();
}

It works good in Java 6 but Java 7 throws exception

它在Java 6中运行良好，但Java 7抛出异常。

Problem disappear if I extract anonymous Object to inner class. Any idea how to fix it without ScriptableObject.get (there are too many places where we create such object and some third party code we use, uses same approach)?

如果我将匿名对象提取到内部类，问题就消失了。知道如何在没有脚本对象的情况下修复它。get(我们创建这样的对象和我们使用的第三方代码的地方太多了，使用相同的方法)?
