Ideally it would be preferred to move jar to a complete nio
implementation and we then
can leave the WindowsPath to take care of this stuff. That said that
would be a relative
big change. I do have a version on my disk but need clean up, test,
performance measurement
and review to get it.
So for now I think it's fine to add this small fix to support the unc.
now sure if the following is better?
637 boolean hasUNC = File.separatorChar == '\\'&&
dir.startsWith("//");
638 while (dir.indexOf("//")> -1) {
639 dir = dir.replace("//", "/");
640 }
641 if (isUNC) // Restore Windows UNC path.
642 dir = "/" + dir;

Hi,
Is there any chance that just using java.nio.file.Path.of will do the
needed cleanup? (or Paths.get)
It seems a shame to spread this kind of adhoc fixup around?

Hi Matthias,
thanks for doing this fix.
I think this can be noted down a bit better, avoiding duplicating the
loop.
Also, please remove the redundant dir.replace(File.separatorChar, '/').
dir = dir.replace(File.separatorChar, '/');
+ String unc = (dir.startsWith("//") &&
(File.separatorChar == '\\')) ? "/" : "";
while (dir.indexOf("//") > -1) {
dir = dir.replace("//", "/");
}
-
pathsMap.get(version).add(dir.replace(File.separatorChar, '/'));
+ // Restore the second leading '/' needed for
the Windows UNC path.
+ dir = unc + dir;
+ pathsMap.get(version).add(dir);
nameBuf[k++] = dir + args[++i];
Best regards,
Goetz.

Subject: [CAUTION] RFR : 8207395: jar has issues with UNC-path
arguments
for the jar -C parameter [windows]
Please review this small fix for allowing windows UNC paths in
the jar -C
parameter.
Currently passing a UNC path to a directory with -C <dir> fails :
c:\testdir>c:\tools\jdk10\bin\jar.exe test.jar -C \\MYMACHINE\subdir
README.txt
Illegal option: s
Try `jar --help' for more information.
With the patch it works .
