Subject: Re: [xwiki-users] Upload of files >2GB fails

Seems to me one of the problems is that the file size is stored in the DB as an 
int for which max value is 2147483647 (and there is probably other related 
issues in the upload and storage process).

I don't understand how you can have the file size displayed correctly in that 
case by the way.

You should create an issue about that on http://jira.xwiki.org/ with steps to 
reproduce it.
