[xwiki-users] Package Import Issue on XWiki 2.2 rc 1

Hello everyone, I've been facing issues importing .xar packages into the new XWiki 2.2 rc 1. The original XWiki was XWiki 2.1.1 stable. The upgrade to XWiki 2.2 rc 1 went fine. However, when I import, all the .xar files attached to the import page disappear. Refresh, log out & log in does not help at all. Only, a tomcat restart helps in getting back the "Available Packages" list on the import page. Then the import works just fine. Has this been reported already.Thank you all.
