Warning when creating new migration profiles on XWiki 14.10.10+

[aubincleme]

Steps to reproduce

• Create a new instance of XWiki 14.10.10 ; configure it with enough memory for the import (I used -Xmx6g)
• Install the confluence migrator ; activate the license
• Start a new migration profile by going on the home page of the Confluence Migrator (using the applications panel entry), and by clicking on "create a new profile".

When creating the profile, the following message appears : 

I believe that this is due to the security improvements that were recently pushed in the core, in particular the issue XWIKI-20386.

To be noted that this message has apparently no impact of the functioning of the migrator. It may just confuse users.

Environnement

• XWiki 14.10.10 coming from the standard Jetty package, running on OpenJDK 11.0.12
• Confluence migrator in version 1.0.14
