Am seeing failures of test_chdir.test_windows_chdir_dos_path on my Windows machine. Reproducible from Windows 10, using windows cmd and cygwin command lines on JDK 8 and 10.
JDK 8 example:
c:\working\working>%JY%\dist\bin\jython.exe -m test.regrtest -v test_chdir
== 2.7.2a1+ (, Oct 16 2018, 11:40:48)
== [Java HotSpot(TM) 64-Bit Server VM (Oracle Corporation)]
== platform: java1.8.0_111
== encodings: stdin=cp850, stdout=cp850, FS=utf-8
== locale: default=('en_AU', 'windows-1252'), actual=(None, None)
test_chdir
test_chdir (test.test_chdir.ChdirTestCase) ... ok
...

1 test failed:

1 fail unexpected:
test_chdir
The immediate cause seems to be the otherwise reasonable re-inclusion of this test for windows in the fix for http://bugs.jython.org/issue2646
That seems to be failing because, as I have learned, it is no longer universal for all windows files and directories to have equivalent short DOS ("8dot3") names.
https://docs.microsoft.com/en-us/windows/desktop/fileio/naming-a-file
https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/fsutil-8dot3name
The setting lives at a filesystem level, and can be read from the command line with the fsutil command
C:\Users\Adam\jython\jython>fsutil 8dot3name query
The registry state is: 1 (Disable 8dot3 name creation on all volumes).
I have a potential fix which basically involves some checks for validity in the unit test itself. I will raise a github PR.

Raised under 2.7 as it seems there is a 2.7.3 and 2.7.4 version in the bugtracker but not 2.7.1 or 2.7.2

Am rerunning the full regrtest suite against some different JDK versions / cygwin etc.
