Having a trailing backspace is not a problem with Jython 2.5 or any Python version.

So this is not an issue for a trailing slash on Windows, just a trailing backslash. Interesting difference.

Blocker for beta 4

After reading source code, it was related to os.lstat and os.stat changes in PosixModule which was made on 2/29/2014 and 4/25/2014:
            String absolutePath = absolutePath(path);

            // round tripping from a string to a file to a string loses
            // trailing slashes so add them back back in to get correct posix.lstat
            // behaviour if path is not a directory.
            if (asPath(path).endsWith(File.separator)) {
                absolutePath = absolutePath + File.separator;
            }
            return PyStatResult.fromFileStat(posix.lstat(absolutePath));

According to the change, it will apppend a backslash(For Windows) to the absolute path if the origin path ends with a backslash. But the posix.lstat will report error if the path ends with a backslash. 
Not sure it's an issue for posix implemation in jnr-posix or the path should not be appended a backslash.

The specific issue raised here seems to be fixed as of https://hg.python.org/jython/rev/e04fa277ce19, however, there is one related failing test still in test_glob to be investigated, test_glob_unicode_directory_with_trailing_slash.

@Kane, thanks for your investigation as well. I have completely changed how we do stat on Windows, plus absolute path calculations, so that we follow closer Java 7 Path support and don't use JNR. (Great package, but I prefer not to have a JNI dependency if possible.)

test_glob now works as of https://hg.python.org/jython/rev/8b2db200158f
