      Description

      Starting from 7u79, the usage string of jar utility mentions the option '-n', though it is not supported in Java 7.
      ----------
      C:\Program Files\Java\jdk1.7.0_79\bin>jar
      Usage: jar {ctxui}[vfmn0PMe] [jar-file] [manifest-file] [entry-point] [-C dir] files ...
      Options:
          -c create new archive
          -t list table of contents for archive
          -x extract named (or all) files from archive
          -u update existing archive
          -v generate verbose output on standard output
          -f specify archive file name
          -m include manifest information from specified manifest file
          -e specify application entry point for stand-alone application
              bundled into an executable jar file
          -0 store only; use no ZIP compression
          -P preserve leading '/' (absolute path) and ".." (parent directory) components from file names
          -M do not create a manifest file for the entries
          -i generate index information for the specified jar files
          -C change to the specified directory and include the following file
      If any file is a directory then it is processed recursively.
      ...
      C:\Program Files\Java\jdk1.7.0_79\bin>jar -n
      Illegal option: n
      Usage: jar {ctxui}[vfmn0PMe] [jar-file] [manifest-file] [entry-point] [-C dir] files ...
      Options:
          -c create new archive
          -t list table of contents for archive
          -x extract named (or all) files from archive
      ...
      ----------
      It looks like a copy-paste error during backporting from Java 8/9.
      Not reproducible with 7u76.
