/**
 * An authorization test using a proxy + spring security. A CXF JAX-WS "double-it" service requires 
 * TLS with client authentication. A CXF proxy service also requires TLS, but with a UsernameToken
 * instead of client authentication. A Camel route is configured to route messages from the proxy to 
 * the service. A client can invoke on the proxy with a UsernameToken over TLS, the proxy is 
 * configured not to authenticate the UsernameToken, but just to process it and store the Subject on 
 * the message. The Camel route instantiates a Processor that takes the Subject name + password and
 * authenticates it via spring security. Spring security also checks to see that the Subject has the 
 * correct role to call the route, which is defined as "boss" in the configuration. On successful 
 * authorization, it passes the call + response to the backend service.
