Summary

Switch jpackage to use jdk.internal.joptsimple package to parse command line arguments instead of the internal implementation.

Problem

jpackage code was inherited from JavaFX with the custom parser of the command line arguments. jpackage supports 61 options; the parser code is not trivial. It is the perfect candidate for using the dedicated library for parsing command-line arguments. Other JDK tools use jdk.internal.joptsimple, so should jpackage.

Solution

Use jdk.internal.joptsimple package to parse command line arguments instead of the internal implementation.

Specification

jpackage will recognize all existing command-line options and also recognize the "-?" option as an alias for the "--help" option.

In addition to the existing format to set the value of an option with a value that is --<option name> <value>, jpackage will recognize the following additional formats:

--<option name>=<value>
-<option name> <value>
-<option name>=<value>

E.g.: to set the value of the "--dest" option to the "output" directory, they can choose one of the following formats:

--dest output
--dest=output
-dest output
-dest=output

Support for these formats is provided by jdk.internal.joptsimple package.
