[XWIKI-16204] SchedulerPlugin related errors when upgrading XWiki to 11.1

I have created a migrator, and after it has run, you can see the deleted pages in the recycle bin:

Yes the only effect is an annoying (but scary) log. Still it really does not looks great to end up with that every time you start XWiki.

Actually from the logs it seems XWiki is still starting and it's "just" some errors in the logs so the severity is a bit less than what I thought. We still need to fix ASAP.

Note: I moved the issue to 11.3RC1 because today is the last day before the 11.2 release and there's no more time. It's a pity since this is a very important issue for our users, causing problems and frustration when they upgrade XWiki.

After the upgrade process was finished, the wiki was running, no strange behavior observed, but I haven't run other tests on the migrated instance. However, the errors were displaying in console on every restart of the instance.

iandriuta: Except a strack trace in the logs, could you confirm it does not prevent XWiki from running?

We've discussed a bit this topic on matrix:

gdelhumeau:
These pages are not removed because they were not part of any XAR. They used to be created by mandatory initializer. Do you think we need a cleaner migrator?

tmortagne:
I don't see much other solution than some migration cleanup considering it's a XWiki Standard war thing, but not sure in which module this migration should go.

gdelhumeau:
Can't we detect mandatory documents that are not necessary anymore? And have a clean mechanism in core?

tmortagne:
Not in this case. We have no idea those document are mandatory documents. In other cases we could maybe imagine listening to mandatory document initializer uninstall event but we don't have that here since it's a WAR jar and there is nothing in those document indicating it's been generated by a mandatory document initializer

gdelhumeau:
Maybe we should introduce a metadata

tmortagne:
Maybe but it's too late now

But we never went further

For #xwiki chat:

Guillaume Delhumeau: I see https://jira.xwiki.org/browse/XWIKI-16073 is still open but there have been several important commits related to it

ah no forget it
rolled back
hmmm
actually this removed the watchlist I think: https://github.com/xwiki/xwiki-platform/commit/2d419c6ed65a447be76beb835f1d2d74279993dd
and it's not been rolled back
I'm trying to find why we don't have the watchlist jar anymore and when it was done (which issue and which release notes)
I'm trying to reply to https://jira.xwiki.org/browse/XWIKI-16204

so it seems to me there's a problem with https://jira.xwiki.org/browse/XWIKI-16073 . Can you confirm that it's a mistake that it hasn't been closed? I don't think it's been fully reverted
and if we rempved the watchlist jar it would explain why the watchlist shceduler jobs are failing now

(since they contain a WatchListJobClass xclass)

gdelhumeau ?
