directory-grouping configuration is not getting persisted via CLI when no servers defined

1). Take a default "wildfly-8.0.0.Final" installation and Start in domain mode. 2). Remove the default servers. /host=master/server-config=server-one/:stop /host=master/server-config=server-one/:remove /host=master/server-config=server-two/:stop /host=master/server-config=server-two/:remove /host=master/server-config=server-three/:stop /host=master/server-config=server-three/:remove 3). Check the "host.xml" file the empty <servers></servers> tag is present. 4) Apply the directory-grouping configuration. /host=master/:write-attribute(name=directory-grouping,value=by-type) 5). Check the "host.xml", It can be seen that the <servers></servers> tag is removed. As the "directory-grouping" information is not persisted in the XML file hence it is lost when we restart the Host controller. So after restart we see the following [domain@localhost:9990 /] /host=master/:read-attribute(name=directory-grouping) { "outcome" => "success" , "result" => "by-server" } Expected result: In "host.xml" file the "directory-grouping" should have persisted (by-type) so that it could survive the host restart.
