[xwiki-devs] [GSOC][WEBDAV] Problem With Core Failing (XWikiCacheStore)

[Vincent Massol]

Yes this bug was introduced by Thomas' recent commit I guess. Thomas  
should be able to answer you tomorrow morning (GMT+1).

Thomas, btw did you check if all XWiki entry points continue to work  
and especially XMLRPC and GWT?

Thanks
-Vincent
