[SOLVED] After upgrade to 2.4 stable I'm flooded with java.lang.IllegalStateException

Usually that exception is a side effect of the load.

The increased load could be due to openHAB trying to apply addon changes every minute.

Can you post the contents of the following files?

  • /etc/openhab2/services/addons.cfg
  • /var/lib/openhab2/config/org/openhab/addons.config

It may help to delete /var/lib/openhab2/config/org/openhab/addons.config so it is regenerated with correct content (see [SOLVED] OH 2.3 missing ComfoAir Binding in PaperUI).
