Bug in host.xml serialization

One is when creating a new server configuration with the help of the console. The new server is created and started and everything works fine, as long you do not restart the host controller. If you do a restart, the host will not start due to a parser error (javax.xml.stream.XMLStreamException: ParseError at [row,col] [Host Controller] Message: JBAS014788: Unexpected attribute 'ref' encountered).
If I remove a "ref" attribute from <server name="test" group="main-server-group" auto-start="false"><socket-bindings ref="standard-sockets" port-offset="777"/> </server> in host.xml, the host starts without a problem.
