      Description

      ADDITIONAL SYSTEM INFORMATION :
      Windows 10

      A DESCRIPTION OF THE PROBLEM :
      sun.nio.fs.WindowsPathParser cannot correctly check the URI at the beginning of "\\.\".
      When I forced sun.nio.fs.WindowsPathParser#isInvalidPathChar to return false, the target file was successfully generated.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      invoke: Files.createFile(Paths.get("\\\\.\\D:\\prn.xml"));

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      no exception
      ACTUAL -
      Exception in thread "main" java.nio.file.InvalidPathException: Illegal character [:] in path at index 5: \\.\D:\prn.xml
