HI,
I have fresh version od Xwiki 12.2 installed at 28.03.2020 14:30. I have installed extension from manager:
OpenID Connect Authenticator
Then jus after installation I go to Extension and click Check for update. Then it find that there is a new version of OpenID Connect Authenticator.
It shouldn’t be that when I install extension it should install up to date one?
After update proces I got:
Hi, first it seems you had 1.18 version installed and the EM has found that there’s a newer 1.18.1 version. I don’t know why you had 1.18, maybe that’s what you installed? (version 1.18.1 was released on 25/3/2020, https://extensions.xwiki.org/xwiki/bin/view/Extension/OpenID%20Connect/OpenID%20Connect%20Authenticator/?viewer=changes&rev1=34.1&rev2=34.2&).
About the “zip file closed” issue you need to click the message as mentioned in the message itself and paste the content here or it’s hard (if not impossible) to help you 
I have downloaded fresh xwiki WAR about 1 hour ago. Click install extension from manager. Then next check for updates and it find update

Ok that’s interesting!
@tmortagne any idea? 
I think problem is that I install only OpenId Connect Authenticator. And it found after it that this library has newer version connected to other extension not installed by me

This is a rare classloader bug which has been hard to debug so and which is usually fixed by restarting the application server.
you mean the same as on below page point 1 and 10 ?
https://xwiki.com/en/Blog/Top10XWikiAppsquestionsandsolutions
On that page the issue is that the last person who saved the page doesn’t have script rights (and thus the velocity macros fail to execute). Nothing to do with the ZIP file closed issue.
