Reflection get nested class

In debugger I've the following object o = {$Proxy0@1045} "Proxy[RMIServer,RemoteObjectInvocationHandler[UnicastRef2[liveRef:[endpoint:127.0.0.1:3233,objID:[645345345:43434324ab:-6eee.-54232323232]]]]"

How can I get an object with this host = 127.0.0.1 and port ? How to cast this object if Proxy class here is dynamic, and I can't use it just like that (Proxy) obj. Thanks in advance!
