Summary

Creation of a Path from a String using java.nio.file.Path.of(String) is now changed to accept strings with the long path prefix \\?\ and the long UNC path prefix \\?\UNC\ on Windows.

Problem

On Windows, Path::of accepts a long absolute path string, but rejects the same string when prefixed with \\?\. The same situation applies to long UNC path strings which instead use the prefix \\?\UNC\.

Solution

If a long path prefix \\?\ or long UNC path prefix \\?\UNC\ is detected, then do not reject the string a priori, but instead strip the prefix, examine the remainder of the string, and accept it if it represents an absolute path in the former case, or a UNC path in the latter.

Specification

There is no visible change to the specification.
