/** A property editor for org.jboss.security.SecurityDomain types. This editor
* transforms a jndi name string to a SecurityDomain by looking up the binding.
* The only unusual aspect of this editor is that the jndi name is usually of
* the form java:/jaas/xxx and the java:/jaas context is a dynamic ObjectFactory
* that will create a binding for any xxx. If there is an attempt to lookup a
* binding before it has been created by the underlying service that provides
* the SecurityDomain, the lookup will return the default security service
* which typically does not implement SecurityDomain. In this case, the editor
* will create a proxy that delays the lookup of the SecurityDomain until the
* first method invocation against the proxy.
