Error starting it

[anonymous]

I am using Arcj + XFCE and I get this error:

~ >>> josm
Unrecognized option: --add-opens=java.desktop/javax.swing.text.html=ALL-UNNAMED
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

How do you download respectively install JOSM? Which version of java do you use?
Might be related to #22193. Does josm-latest work?

@anonymous: if you can, modify the josm start script (which josm, probably /usr/bin/josm) and add set -ex after the first line. You can then paste the output here.

I did that and here is the output:

By the way I have installed it via the Manjaro's repositories, but installing it as flatpak makes it work.

See ​https://bugs.archlinux.org/task/72953. Arch should use our start script (see source:trunk/native/linux/tested/usr/bin/josm​ ) which correctly adds flags based off of the java version.
