Starting JOSM.exe with another profile not working ("Changing the directory base name" with installed josm not possible)

[negreheb]

What steps will reproduce the problem?

1. Download .msi from https://josm.openstreetmap.de/
2. Start JOSM normally with the windows-shortcut in the startmenu - working perfectly fine
3. Creating a new profile for working with OpenHistoricalMap
4. Reading https://josm.openstreetmap.de/wiki/Help/Preferences
5. Copying the \AppData\Local\JOSM to \AppData\Local\JOSM-OHM and integrating the properties from \AppData\Roaming\JOSM so i can change them
6. Trying to use with \AppData\Local\JOSM\app\josm-custom.jar with the command java -Djosm.dir.name=JOSM-OHM -jar josm-custom.jar from within the JOSM-OHM\app\-Folder leads to an java-version-error.

What is the expected result?

Starts like the the regular JOSM.
It seems every instruction everywhere is expecting the usage of an downloaded .jar and not an installed JOSM on Windows.

What happens instead?

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/openstreetmap/josm/gui/MainApplication has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0
It seems JOSM does not pass the options correctly about Java.

Please provide any additional information below. Attach a screenshot if possible.

Using windows 11, not windows 10.

As already written in the ​forum you need to use java 11+. Java 8 will not work. You have two options:

• Set the correct paths to use the JRE ship with the JOSM windows installer
• Upgrade your default system java version to 11 or higher

[taylor.smock]

Alternatively you can write a batch file that changes app/JOSM.cfg to have the OHM profile path.
