:reload operation on standalone server changes server's java.naming.factory.url.pkgs system property. After each restart "org.jboss.as.naming.interfaces:" is prepended to the property.

The property content after couple of :reloads
"java.naming.factory.url.pkgs" => "org.jboss.as.naming.interfaces:org.jboss.as.naming.interfaces:org.jboss.as.naming.interfaces:org.jboss.as.naming.interfaces:org.jboss.as.naming.interfaces:org.jboss.as.naming.interfaces:org.jboss.ejb.client.naming"

Steps to reproduce:
1) Start standalone server
2) Connect to it using CLI
3) issue :reload operation:
[standalone@localhost:9999 /] :reload
4) check the property:
[standalone@localhost:9999 /] /core-service=platform-mbean/type=runtime:read-attribute(name="system-properties")
