An unexpected error occurred.

[sebastien.merle67@…]

Information, I use Google Translate, to translate my messages into English, basically I am French.

What steps will reproduce the problem?

• I was in a mapping session, I downloaded several layers.

What is the expected result?

By wanting to close JOSM I found myself with an error message which indicates to me that an error occurred.

What happens instead?

JOSM refuses to close, and gives me an error message.

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

Closed as duplicate of #22088.
This should be fixed when I merge in the changes for #22088.

The flatpak instance is using the JOSM start script, and it doesn't properly detect the Java version (the current script version uses the path to the Java executable).
