      Description

      Current jshell options are --

          -classpath <path> Specify where to find user class files
          -cp <path> Specify where to find user class files
          -startup <file> One run replacement for the start-up definitions
          -nostartup Do not run the start-up definitions
          -feedback <mode> Specify the initial feedback mode. The mode may be
                               predefined (silent, concise, normal, or verbose) or
                               previously user-defined
          -q Quiet feedback. Same as: -feedback concise
          -qq Really quiet feedback. Same as: -feedback silent
          -v Verbose feedback. Same as: -feedback verbose
          -J<flag> Pass <flag> directly to the runtime system.
                               Use one -J for each runtime flag or flag argument
          -R<flag> Pass <flag> to the remote runtime system.
                               Use one -R for each remote flag or flag argument

      java current double-dash options are --

          -cp <class search path of directories and zip/jar files>
          -classpath <class search path of directories and zip/jar files>
          --class-path <class search path of directories and zip/jar files>
                        A : separated list of directories, JAR archives,
                        and ZIP archives to search for class files.
          -p <module path>
          --module-path <module path>...
                        A : separated list of directories, each directory
                        is a directory of modules.
          --upgrade-module-path <module path>...
                        A : separated list of directories, each directory
                        is a directory of modules that replace upgradeable
                        modules in the runtime image
          -m <module>[/<mainclass>]
          --module <modulename>[/<mainclass>]
                        the initial module to resolve, and the name of the main class
                        to execute if not specified by the module
          --add-modules <modulename>[,<modulename>...]
                        root modules to resolve in addition to the initial module.
                        <modulename> can also be ALL-DEFAULT, ALL-SYSTEM,
                        ALL-MODULE-PATH.
          --limit-modules <modulename>[,<modulename>...]
                        limit the universe of observable modules
          --list-modules [<modulename>[,<modulename>...]]
                        list the observable modules and exit
          --dry-run create VM but do not execute main method.
                        This --dry-run option may be useful for validating the
                        command-line options such as the module system configuration.

      Of these, --class-path, --module-path, --add-modules, and maybe --upgrade-module-path seem appropriate for jshell.

      Proposed for jshell --

          --class-path <path> Specify where to find user class files

          --module-path <module path>... directory of modules.
          -p <module path>

          --upgrade-module-path <module path>... directory of modules that replace upgradeable modules

          --add-modules <modulename>[,<modulename>...] root modules to resolve

          --startup <file> One run replacement for the start-up definitions

          --no-startup Do not run the start-up definitions
          -n

          --feedback <mode> Specify the initial feedback mode. The mode may be
                               predefined (silent, concise, normal, or verbose) or
                               previously user-defined

          -q Quiet feedback. Same as: --feedback concise

          -s Really quiet feedback. Same as: --feedback silent

          -v Verbose feedback. Same as: --feedback verbose

          -J<flag> Pass <flag> directly to the runtime system.

          -R<flag> Pass <flag> to the remote runtime system.
