Closed as duplicate of #22183.
@chris: If this happens reliably for you, can you please give me the information I asked for in comment:6:ticket:22183? I'll copy it here as well.

I have been unable to reproduce the bug (I set up JOSM in a restart loop, and it never say the same bug you did over 1800 starts).

---

For those running into this problem, can you please run JOSM with the --trace option (on Ubuntu Linux, josm --trace).

Please note that --trace may expose sensitive information (specifically login information for various services, like OSM), so please only paste stack traces. Stack traces look like this:

java.lang.NoClassDefFoundError: Could not initialize class org.openstreetmap.josm.actions.SessionSaveAction
	at org.openstreetmap.josm.gui.MainMenu.<init>(MainMenu.java:181)

	at org.openstreetmap.josm.gui.MainApplication.main(MainApplication.java:741)

I am specifically interested in a java.lang.NullPointerException stack trace. It should have java.lang.ExceptionInInitializerError and java.util.concurrent.ExecutionException around it (please copy those as well).

Side note: I'm getting ready to release a new stable, and I'd really like to have this bug fixed. I'm aiming for a release today (August 29, 2022, UTC-6), but if you can get me the information I need to fix this bug, I will be more than happy to do the release after I fix it.

Seriously, I want to fix this. There have been 16 duplicate bug reports (which is a lot -- many people don't bother reporting bugs, so thank you for taking the time to do so), most of which were anonymous. Which makes followup really hard. It wouldn't matter if the bug report had the information I actually need, but it doesn't. :(

In 18570/josm:

Fix #22183: NoClassDefFoundError: Could not initialize class org.openstreetmap.josm.actions.SessionSaveAction

This was caused by JOSM detecting that it had started in IPv6 mode, but no IPv6
network was available. When this occurs, JOSM immediately sets a preference key
and restarts so that users are not confused about a lack of network connectivity.

The JOSM restart action then proceeds to attempt to save any active layers, but
since this occurs during startup, there are no active layers and the save actions
have not yet been initialized. The save actions cannot be initialized before
contentPanePrivate has been initialized, but the IPv6 call is done prior to
that happening, which may then trigger a JOSM restart, which calls exitJosm,
which then calls the save layers actions.
