Possible java.nio.file.FileAlreadyExistsException when trying to save a job status

Tested on a clean instance of XE 8.2, configured on MySQL 5.7 (with a new database), using Windows 10 with 64-bit, on Chrome 51 - private mode

Actual result:

• I opened the instance, installed all the features through DW and got in the end the XWiki Main page displayed in browser.
• In that moment, it was triggered in the console this warning:

• This warning doesn`t stop you to perform any action you want in XWiki.
• If I restart the instance and open it in the browser, the warning will not be displayed anymore.
• The warning appears only at a first access of the instance in browser after you made the installation with DW.

Expected result:

• I expect to not see warnings like this in the console when I access the instance for the first time. Even if apparently no impact was noticed on the functionality of XWiki, user could think that something was wrong during the install because the message of the warning: " Failed to save job status"
