Description
Summary
-------

Finalize the Packaging tool (jpackage).

Problem
-------

This CSR proposes to standardize jpackage, which was introduced
as an incubating tool in JDK 14 (  JDK-8200758 JEP 343 ) and updated in JDK 15.
The incubated tool has received a number of rounds of feedback that have resulted in improvements, but is largely the same. 

Solution
--------
Remove "incubator" from the "jdk.incubator.jpackage" namespace.

Specification
-------------

The change for this CSR is to remove "incubator" from the jpackage namespace, and adjust source files, makefiles, and automated test accordingly.

jdk.incubator.jpackage --> jdk.jpackage.

API Documentation

```
    /**
     * Defines the Java Packaging tool, jpackage.
     *
     * <p>jpackage is a tool for generating self-contained application bundles.
     *
     * <p> This module provides the equivalent of command-line access to <em>jpackage</em>
     * via the {@link java.util.spi.ToolProvider ToolProvider} SPI.
     * Instances of the tool can be obtained by calling
     * {@link java.util.spi.ToolProvider#findFirst ToolProvider.findFirst}
     * or the {@link java.util.ServiceLoader service loader} with the name
     * {@code "jpackage"}.
     *
     * @implNote The {@code jpackage} tool is not thread-safe. An application
     * should not call either of the
     * {@link java.util.spi.ToolProvider ToolProvider} {@code run} methods
     * concurrently, even with separate {@code "jpackage"} {@code ToolProvider}
     * instances, or undefined behavior may result.
     *
     * @moduleGraph

          A comma (",") separated list of modules to add.
          This module list, along with the main module (if specified)
          will be passed to jlink as the --add-module argument.
          if not specified, either just the main module (if --module is
          specified), or the default set of modules (if --main-jar is
          specified) are used.

          A ; separated list of paths
          Each path is either a directory of modules or the path to a
          modular jar.

          This option can be used multiple times.
--jlink-options <jlink options> ���
          A space separated list of options to pass to jlink
          If not specified, defaults to "--strip-native-commands

          Path of the predefined runtime image that will be copied into
          the application image

          These options are added to, or used to overwrite, the original
          command line options to build an additional alternative launcher.
          The main application launcher will be built from the command line
          options. Additional alternative launchers can be built using
          this option, and this option can be used multiple times to
          build multiple additional launchers. 

--arguments <main class arguments> ���
          Command line arguments to pass to the main class if no command
          line arguments are given to the launcher

Comments
For --module-path, I assume the path separator is platform dependent. Moving to Approved.
16-10-2020

Please include the current command line interface as well; I'd like to take another look at if before the final approval. Moving to Provisional.
14-10-2020

Are you asking for a copy/paste of everything that was in the incubator approval ? I am not sure that is needed, since it isn't changing. This CSR is just about removing incubator and there's the updated API doc for the ToolProvider in this CSR.
14-10-2020

Moving to Provisional, not Approved. Please present some form of the finalized API in the CSR and have another enginer review the request before it is Finalized.
13-10-2020

There are no command line interface changes. There is no public API in jpackage, other than implementing the ToolProvider. The only change here is changing the module and package names from jdk.incubator.jpackage to jdk.jpackage
06-10-2020

Moving to Provisional. Before the request is Finalized, please include the exact interfaces (API, command line, etc.) that will be removed and added.
