Description
With the end of Java WebStart and public JRE availability from Oracle (end of 2020) we need to find another deployment technology that matches our needs:
- still offer a simple jar for power users, and Linux distributions that include the Java and JavaFX runtimes, as they manage the security updates themselves
- provide a simple way for Windows and macOS users to get JOSM, Java and JavaFX runtimes
- provide a light mechanism to get JOSM latest updates every day
- make sure users get Java security updates if we ship the runtimes ourselves
Java 9 introduced a new tool (jlink) to create custom Java runtimes that only include the classes needed for an application. It allows to create smaller runtimes and also gives a significant boost when starting the JVM (less stuff to load).
I never considered it seriously until today because jlink does not allow cross-platform builds. So if we go this way, we need to get three build servers (Linux, Windows, macOS).
I found today an open source project that managed to do it. The results in size are quite impressive (less than 40 Mb). This is achieved using Azure Pipelines: Microsoft provides a free offer for open source projects (10 free parallel jobs with unlimited minutes).
I will try to build native runtimes with OpenJDK 11, JavaFX 11 and JOSM to see if it works :)

In the course of #18319 a jpackage-based script (which uses jlink under the hood) has been developed for macOS. Could be useful for Windows too.

@stoecker: right now the jpackage-based Windows installer installs JOSM silently without any GUI.
There is a --license option which displays a GUI to ask user for license agreement:
Is it something we want for JOSM? The text will always be displayed in English.

The GPL is no EULA. It must not be accepted to use the software, so I don't think that's useful.

Replying to stoecker:

OK, thanks!

Ah it seems I totally misunderstood what jlink was capable of. We cannot create a single image that runs on different OS, but we should be able on a given host to create images targeted for a different OS. So we might not need the Microsoft offer at all, if we can create the images on our Linux server.
