Java JacORB 3.x中本地对象的便携式拦截器使用不当？

JacORB 3中如何将便携式拦截器用于本地对象的实现发生了变化，如下所示： 发行说明中指出：“为本地对象正确实现了可移植拦截器。” 这一新的实施似乎带来了一些问题；重现问题的最简单方法 是从sas演示（jacorb附带的演示）修改GssUpServer.java：

GssUpClient.bat之后的堆栈跟踪：

上述代码在JacORB 2.3.1中运行良好。解决此问题的简单方法是将属性

jacorb.isLocalHistoricalInterceptors

设置为true； 但是，某些“内置”方法（例如

\u is\u a（）

）不遵守此标志（因为这些方法直接使用

is\u really\u local（）

检查对象的局部性）。看来 这些“内置”方法调用以前从未在本地调用时使用过拦截器

因此，我的观察结果是：

jacorb3.x似乎破坏了一些用于本地调用的可移植拦截器（确切地说，是需要连接对象的拦截器…）

JacORB 3.x似乎是第一个使用便携式拦截器对

\u is\u a（）

，

\u不存在（）

，

\u接口（）

，

\u get\u组件（）进行本地调用的JacORB

第一个问题是可以解决的，因为有一个属性使JacORB 3.x与旧版本一样工作。第二个（加上第一个）似乎真的很麻烦

---

有没有其他人注意到这种行为，并且能够证实我的怀疑，这确实是JacORB 3.x中的一个缺陷，或者我遗漏了什么

带有本地调用的内置便携式拦截器应能正常工作；这听起来像个虫子。事实上，听起来像。我也输入了

恐怕我没有看到这一点，因此回复很晚；请注意这里有官方的JacORB邮件列表：bugzilla谢谢！我们在软件中对此做了一个快速补丁，之后我有点忘记了这个问题。我可能应该马上用你的bugzilla:）
