[xwiki-users] API/Configuration to refer the newly added property in xwiki.cfg without server restart?

Whenever i add a new property in xwiki.cfg file, to refer that property in my java code, i need tomcat server restart otherwise that property is not visible. Is there a api/configuration can refer the newly added property in xwiki.cfg file without server restart? Here is how i get the newly added property from xwiki.cfg file String adminData=xwikiContext.getWiki().getConfig().getProperty("adminData"); Thanks.
