I have problem when my Jython program tries to execute
Windows batch file which is the current directory, but this directory
is not the directory the program was started in.

Test program: dir_batch_test.py is attached.

In CPython this works well:

C:\share\mn>python dir_batch_test.py
Trying to execute: "batch_test.bat" in dir: "C:\share\mn\test"
file exists: C:\share\mn\test\batch_test.bat

C:\share\mn\test>time /t
10:16


In Jython I got strange exception:

C:\share\mn>jython dir_batch_test.py
Trying to execute: "batch_test.bat" in dir: "C:\share\mn\test"
file exists: C:\share\mn\test\batch_test.bat
Exception while trying to execute batch_test.bat
Traceback (most recent call last):
  File "dir_batch_test.py", line 21, in execute_cmd_args
    proc = subprocess.Popen(args, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
  File "D:\jython2.5.3\Lib\subprocess.py", line 751, in __init__
    self._execute_child(args, executable, preexec_fn, close_fds,
  File "D:\jython2.5.3\Lib\subprocess.py", line 1265, in _execute_child
    raise OSError(e.getMessage() or e)
OSError: Cannot run program "batch_test.bat" (in directory "C:\share\mn\test"): CreateProcess error=2, The system cannot find the file specified

I think this is a bun in Jython subprocess module.
