Each proxy instance has an associated invocation handler object, the one that was passed to its constructor.

Proxy has one serializable field, h, which contains the invocation handler for the proxy instance.

An interface method invocation on a proxy instance will be encoded and dispatched to the invocation handler's invoke method as described below.

In other words, the public, non-final methods of java.lang.Object logically precede all of the proxy interfaces for the determination of which Method object to pass to the invocation handler.

If a proxy instance contains an invocation handler that is not assignable to java.io.Serializable, however, then a java.io.NotSerializableException will be thrown if such an instance is written to a java.io.ObjectOutputStream.

Portable Object Adapter (POA) : The CORBA object responsible for splitting the server side remote invocation handler into the remote Object and its Servant.
