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My conclusion : The snap contains an outdated JRE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 a 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 My conclusion is that the snap pack contains the outdated Java.
