Java compact2, compact3 java.rmi.server Class RemoteObjectInvocationHandler（JDK8）

RemoteObjectInvocationHandler implements this method as follows:

If method is one of the following methods, it is processed as described below:

• Object.hashCode: Returns the hash code value for the proxy.
• Object.equals: Returns true if the argument (args[0]) is an instance of a dynamic proxy class and this invocation handler is equal to the invocation handler of that argument, and returns false otherwise.
• Object.toString: Returns a string representation of the proxy.

Otherwise, a remote call is made as follows:

• If proxy is not an instance of the interface Remote, then an IllegalArgumentException is thrown.
• Otherwise, the invoke method is invoked on this invocation handler's RemoteRef, passing proxy, method, args, and the method hash (defined in section 8.3 of the "Java Remote Method Invocation (RMI) Specification") for method, and the result is returned.
• If an exception is thrown by RemoteRef.invoke and that exception is a checked exception that is not assignable to any exception in the throws clause of the method implemented by the proxy's class, then that exception is wrapped in an UnexpectedException and the wrapped exception is thrown. Otherwise, the exception thrown by invoke is thrown by this method.

The semantics of this method are unspecified if the arguments could not have been produced by an instance of some valid dynamic proxy class containing this invocation handler.
