/**
 * This 'proxy' class exists in order to permit the client/server/endpoint classes from barfing when loading (ie, the JVM classloader),
 * since the classloader only checks ONE level deep for deps, not TWO levels deep.
 * 
 * This exploits the class loading behavior, but it nicely permits us to choose if we want to use UDT or not, without
 * classloading complications
