Support for the endJade argument is maintained to provide backward compatibility for existing applications. It is recommended that your applications use the startAppParameters and endAppParameters arguments.
Specify the optional endJade argument if you want to specify your own parameters (that is, user‑defined command line arguments) in addition to the JADE-specific ones that are required. If you specify this argument, it must be the last of the JADE arguments before the first of your own parameters.
