2.5 issues after upgrade

Since S1566, when clearing the cache, you will need to start OH then restart again after things settle down. There used to be a lot of errors in the log, but these seem to be mostly cleaned up.
If you don’t, many people see this issue…

My understanding is that addons.config is the result of aggregating all of the sources (addons.cfg and Paper UI). Also, if you touch a line in addons.cfg, that line takes priority.
