        public List<String> getCommandLine​(String executable,
                                           String[] arguments)

        Specific implementation that quotes all the command line.

        Workaround for

        From cmd.exe /? output:

              If /C or /K is specified, then the remainder of the command line after
              the switch is processed as a command line, where the following logic is
              used to process quote (") characters:
              1.  If all of the following conditions are met, then quote characters
              on the command line are preserved:
              - no /S switch
              - exactly two quote characters
              - no special characters between the two quote characters,
              where special is one of: &<>()@ˆ|
              - there are one or more whitespace characters between the
              the two quote characters
              - the string between the two quote characters is the name
              of an executable file.
              2.  Otherwise, old behavior is to see if the first character is
              a quote character and if so, strip the leading character and
              remove the last quote character on the command line, preserving
              any text after the last quote character.

        Always quoting the entire command line, regardless of these conditions appears to make Windows processes invoke successfully.
