Message9770

Observed on Windows 7 with Jython 2.7rc2 test.test_file2k reports one failure:

...
test_unicode (__main__.StdoutTests) ... Traceback (most recent call last):

FAIL: test_unicode (__main__.StdoutTests)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "C:\jython\2.7rc2\Lib\test\test_file2k.py", line 737, in test_unicode
    check_message(u'15\u20ac', "utf-16-le", '1\x005\x00\xac\x20')

    self.assertEqual(process.returncode, 0)
AssertionError: -1 != 0

The message about the encoding emerges, I think, from the stderr of the subprocess, which then returns the much less useful error status that fails the test.
