barcontrol 25: Java Nullpointer error when closing GUI on Windows x64 #15

Just got the following error when closing the GUI: grafik

Here's the complete stacktrace as text:

Note: Some INDEX work was running at the moment. BAR seemed to be busy upgrading an imported index-db from an earlier version:

2024-10-26 20:38:06> INDEX: 58.8%, estimated rest time 0h:00min:00s

BTW, the "estimated rest time" is always displayed as 0h:00min:00s. Another bug?

After that crash I'm no longer able the start the GUI again. It closes instantly again with following output in barcontrol.log:

Even worse: After restarting barserver, all backups in the database are marked as incomplete and purged. Luckily I was fast enough to stop BAR again before it actually could physically delete my backups on the strorage:

This looks like some serious problems. I think I will not start v25 again until it is clear what's happing here.

Okay, I was brave enough to re-run barserver (with chmod -w and chattr +i on all backup files) and after these kind of entries in bar.log the GUI now runs again, but all listed backups are gone now.

Also, the automatic re-indexing is not triggered for some reason.
