Original 2019 plan:

On the current roadmap, the first version will be released end of October. A macro planning for a Java 8 => Java 11 transitions for all JOSM users would roughly look like this:
- September 2019: we start testing OpenWebStart on all platforms. Likely we'll found a lot of bugs
- November 2019 : first OpenWebStart version. Unlikely to fix all bugs we'll find
- Somewhere in 2020: OpenWebStart version without any bug impacting us, we start asking everyone to switch
- End of 2020: End of Java WebStart support by Oracle for Java 8. We force everyone to switch
- Somewhere in 2021: Enough JOSM users have switched to OpenWebStart so we can consider moving the codebase to Java 11.

New 2021 plan:

- 2021-03-28: ask Oracle Java WebStart users to switch to OpenWebStart => r17679
- 2021-08-22: new Windows package that includes Java 16 => r18151:18155
- 2021-08-22: include JavaFX 16 in macOS and Windows packages => r18161
- 2021-08-22: update JNLP files to request Azul JVM from OpenWebStart as it includes JavaFX => r18158:18159
- 2021-08-22: update Debian/Ubuntu launch script to depend on openjfx => r18160
- 2021-09-15: Java 17 is released. Switch macOS / Windows packages to Java 17 and JavaFX 17, update Debian/Ubuntu launch script to prefer 17 over 11 and 8 => r18225
- 2022-04-21: Ubuntu 22.04 LTS is released and ships Java 17 (note: `default-jre` is Java 11)
- 2022-11-25: OpenWebStart [https://github.com/karakun/OpenWebStart/issues/495 adds Java 17] to their [https://download-openwebstart.com/jvms.json JVM list] => [https://github.com/karakun/OpenWebStart/commit/3a259ad0a10ce4b913f30c69bdbffccb340bdd5d done]
- somewhere in 2023/2024: Enough JOSM users are now using Java 17+ so we can consider moving the codebase to Java 17.
- 2024-04-xx: Ubuntu 24.04 LTS is released and ships Java 17+ as default; Debian Bookworm already ships Java 17 as default.
