Seems you have configured an JRE version 11 to be used by default. josm-tested.jar is started via the JRE, it cannot search for a different one.

See the copy of my Terminal :

xxxxx:~$ java -version
openjdk version "21.0.3" 2024-04-16
OpenJDK Runtime Environment (build 21.0.3+9-Ubuntu-1ubuntu1)
OpenJDK 64-Bit Server VM (build 21.0.3+9-Ubuntu-1ubuntu1, mixed mode, sharing)
xxxxx:~$

Also
Josm is installed in Ubuntu as a snap, thus their favorite Java is/should be in that snap (?)
My conclusion : The snap contains an outdated JRE

Thx,

The popup just warns that JOSM will soon no longer support JRE 11. Just press OK and I guess that the snap will be updated once JOSM really requires a higher JRE version.
Maybe ask the creator of the snap to confirm this.

Note that the JOSM snap is unofficial and has some issues. Taking a look at your status report, I find strange settings for your System property file.encoding and you seem to miss some VM arguments. Both could lead to other problems. If you are looking for an official package, please, use our Ubuntu packages.

I have not used a josm-tested.jar I used the App Manager in Ubuntu, which resulted in installing a Josm snap. In Ubuntu 24 this is the only version which can be installed via the App Manager. I checked all version of Java on my machine and openjdk version "21.0.3" 2024-04-16 is not only the active version, but also the only version. There is no Java 11. Josm is still functional, so it must have access to a Java version. My conclusion is that the snap pack contains the outdated Java.
