Opening preferences or preset preferences does nothing and block JOSM

[baptistemm@…]

What steps will reproduce the problem?

I use the flatpak version from ​https://github.com/flathub/org.openstreetmap.josm/pull/95 (version 18940)
If I click Edit->Preferences... or Imagery->Imagery Preference, nothing happens and furthermore, the UI does not respond anymore, I even cannot close the josm window

Running with --debug does not show particular error or fatal message.
I also launched with --skip-plugins and that does not work either.

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

I wasn't able to reproduce on Fedora Silverblue using the linked flatpak version from ​https://github.com/flathub/org.openstreetmap.josm/pull/95 (r18940).

Can you get us a thread dump?
General steps (outside of flatpak) are as follows:

$ jps
9543 josm.jar
11580 Jps
$ jstack ${PID from jps}

Cannot reproduce on another computer

If @baptistemm can reproduce on the original computer and give us the thread dump, it would still be a valid ticket.
There is probably something causing the deadlock which needs to be fixed. And it is hard to fix without knowing what is causing it.

cannot even reproduce on the machine where I initially had the issue. sorry

[taylor.smock]

Those are the worst bugs to fix.

Thanks for getting back to us.
