Admin Console error when editing group with non-local members
There is a usage in the form of webManager.userManager.getUser(member) in the group-edit.jsp file. The member is of type JID, but it is converted to string when called. And it comes to getUser method as "firstname.lastname@example.org". This is "java.lang.IllegalArgumentException: The input 'email@example.com' is not a valid JID node part: Contains prohibited code points." causing error.
