typical usage pattern follows below:
public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
//do some processing before the method invocation
//invoke the method
Object result = method.invoke(proxy, args);
//do some processing after the method invocation
return result;
}

| the proxy instance on which the method was invoked |
method
| the method invoked on the proxy instance |
args
| an array of objects containing the parameters passed to the
method, or null if no arguments are expected.
Primitive types are boxed. |
Returns
- the result of executing the method. Primitive types are boxed.
Throws
Throwable
| the exception to throw from the invoked method on the proxy.
The exception must match one of the declared exception types
of the invoked method or any unchecked exception type. If not
then an UndeclaredThrowableException is thrown
