The groups displayer store values with a coma at the end

If you create a new wiki and then consult the list of objects of class "XWiki.XWikiGlobalRights", the response return the property "groups" with a "," at the end.
I create a new wiki. And right after that I do a REST request with the URL:

".../rest/wikis/testcamille/spaces/XWiki/pages/XWikiPreferences/objects/XWiki.XWikiGlobalRights/1/"
We've got the answer :

<object>

<value/>
</property>
</object>

On the above response we see "<value>XWiki.XWikiAllGroup,</value>" with a comma at the end despite it is the only one element of the list.
For the answer of the REST request "http://.../rest/wikis/testcamille/spaces/XWiki/pages/XWikiPreferences/objects/XWiki.XWikiGlobalRights/0/" the property value of "groups" is correct.
