   (to execute a source-file program)
   
   Arguments following the main class, source file, -jar <jarfile>,
   -m or --module <module>/<mainclass> are passed as the arguments to
   main class.
   
   where options include:

   -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 elements, each element is a file path
   to a module or a directory containing modules. Each module is either
   a modular JAR or an exploded-module directory.
   --upgrade-module-path <module path>...
   A ; separated list of elements, each element is a file path
   to a module or a directory containing modules to replace
   upgradeable modules in the runtime image. Each module is either
   a modular JAR or an exploded-module directory.
   --add-modules <module name>[,<module name>...]
   root modules to resolve in addition to the initial module.
   <module name> can also be ALL-DEFAULT, ALL-SYSTEM,
   ALL-MODULE-PATH.
   --enable-native-access <module name>[,<module name>...]

   list observable modules and exit
   -d <module name>
   --describe-module <module name>
   describe a module and exit
   --dry-run create VM and load main class but do not execute main method.
   The --dry-run option may be useful for validating the
   command-line options such as the module system configuration.
   --validate-modules
   validate all modules and exit
   The --validate-modules option may be useful for finding
   conflicts and other errors with modules on the module path.
   -D<name>=<value>
   set a system property
   -verbose:[class|module|gc|jni]
   enable verbose output for the given subsystem
   -version print product version to the error stream and exit
   --version print product version to the output stream and exit
   -showversion print product version to the error stream and continue
   --show-version
   print product version to the output stream and continue
   --show-module-resolution
   show module resolution output during startup
   -? -h -help
   print this help message to the error stream
   --help print this help message to the output stream
   -X print help on extra options to the error stream
   --help-extra print help on extra options to the output stream
