python之在 Jython 中使用时 inspect.py 的问题

我正在使用用 Jython 开发的应用程序。当我尝试在其中使用 inspect.py 时，它显示错误消息。

我的代码是这样的

import inspect,os,sys,pprint,imp 
def handle_stackframe_without_leak(getframe): 
    frame = inspect.currentframe() 
    try: 
        function = inspect.getframeinfo(getframe) 
        print inspect.getargvalues(getframe) 
    finally: 
        del frame 
# 
def raja(a): 
    handle_stackframe_without_leak(inspect.currentframe()) 
    print a 
# 
def callraja(): 
    handle_stackframe_without_leak(inspect.currentframe()) 
    raja("raja@ad.com") 
# 
callraja() 
raja("raja@ad.com") 
# 

当我使用 python.exe 运行它时，没有任何问题。但是，在应用程序中使用它会引发以下错误

请您参考如下方法:

您是否尝试过使用 Jython 在命令行上运行您的程序(在应用程序之外)？当我使用 Jython 2.2.1 或 Jython 2.5.0 运行您的程序时，我得到与 Python 相同的输出。
