我試圖使用ByteBuddy的具體類動態定義sublclass如下反思錯誤時創建的谷歌應用程序使用ByteBuddy引擎
Class<? extends MyConcreteClass> dynamicType = new ByteBuddy()
.subclass(MyConcreteClass.class, ConstructorStrategy.Default.DEFAULT_CONSTRUCTOR)
.name(dynamicClassName)
.annotateType(MyConcreteClass.class.getDeclaredAnnotations())
.make()
.load(MyConcreteClass.class.getClassLoader())
.getLoaded();
此代碼從JUnit測試中工作的一類，但是當我在Google App Engine下運行它，我會得到以下例外。

執行方法make()時拋出異常。
有沒有辦法在GAE下進行這項工作？
