Unable to restart safely

Hi,

After updating plugins and then upgrading Jenkins from 2.479.1 to 2.479.2, I’m unable to successfully restart Jenkins using the Restart Safely option. This happens on the two windows-based apps I’ve updated Jenkins on.

I see the following repeated in the logs:

WARNING h.s.HttpSessionContextIntegrationFilter2#hasInvalidSessionSeed: Encountered IllegalStateException trying to get a user. System init may not have completed yet. Invalidating user session.

The only way around has been to logon to the windows server and restart the service from there. I tried downgrading and re-upgrading with no change. Any ideas are appreciated.
