Can JDK-8190546 be re-opened or "how do I delete a file ending with a space on Windows"

[Maxim Kartashev]

Win32 documentation [1] kind of discourages the use of space at the very
end of a file name. Based on that, JDK-8190546 (File.toPath() reject
directory names with trailing space) had been closed a long time ago. I
would like to poll the public on the matter of re-opening the bug.

There isn't anything new that I can throw in support of allowing JDK to
work with such file names. But the old points can perhaps be re-visited.
AFAIU, the only reason to explicitly forbid that (see
WindowsPathParser.normalize()) was that the parsing is based on Windows
documentation like [1]. That documentation says the following:
"Do not end a file or directory name with a space or a period. Although the
underlying file system may support such names, the Windows shell and user
interface does not"
Indeed, it's hard or even impossible to create such a file using "normal"
windows GUI, but you can use that GUI to delete such a file. In Java, you
can't do either. Working in a cygwin terminal, you can fairly easily create
a file name ending with a space. And when you turn to your Java-based IDE
to delete it, you get an error from the very basic level of NIO that you
can't overrule, which seems to be quite unfortunate.

If there's any interest in resolving this - or at least not enough
opposition to let it be resolved - I am willing to make the necessary
changes and open a PR.
