/**
*
* ServerFactory that sets up a standalone server using modular classloading.
*
*
* To use this class the jboss.home.dir system property must be set to the
* application server home directory. By default it will use the directories
* {$jboss.home.dir}/standalone/config as the configuration directory and
* {$jboss.home.dir}/standalone/data as the data directory. This can be overridden
* with the ${jboss.server.base.dir}, ${jboss.server.config.dir} or ${jboss.server.config.dir}
* system properties as for normal server startup.
*
*
* If a clean run is wanted, you can specify ${jboss.embedded.root} to an existing directory
* which will copy the contents of the data and configuration directories under a temporary folder. This
* has the effect of this run not polluting later runs of the embedded server.
