Aop在GAE上工作不正常 #75

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
版本: rev576

本地测试                Pass
GAE Junit               Pass 
GAE 本地服务器测试      Fail

原本预计只有几个预期的fail,结果大部分Aop测试fail.都fail在同
一个地方:
Aop增强klass后,生成的实例,转换为超类引用时,报: ClassCast
无论使用Mirror.me.born(),还是直接newInstance,或者通过获取特定构
造方法后创建
实例,赋值给超类变量时均报错!
例如:
Class<Aop1> newClass = classAgent.define(Aop1.class);
Mirror<Aop1> mirror = Mirror.me(newClass);
Aop1 obj = mirror.born("Nutz"); //报错!
Aop1 a1 = newClass.getConstructor(String.class).newInstance("Nutz"); //报错!
然而,调用:
System.out.println(obj.getClass().getSuperclass());
打印的却是正确无误的: class org.nutz.aop.asm.test.Aop1

非常神奇,创建对象不会出任何错误,赋值时才报错!
Asm 3.x 都换过了.

不敢肯定是否为GAE的Bug

用 Javassist 写个简单的 Main 函数，会不会也报同样的错误呢？

换到 ASM 的实现后，这个问题还会重现吗？

事实证明, 是GAE的问题. 我换上1.3.0的 GAE SDK后, 就一切正常了!
