[jdom-interest] Moving Children

Sorry, you guys are correct. As I said, it WAS
a long night....

How about using reflection?

Method c = = whatever.getClass().getMethod(...... <clone> ....)
c.invoke(whatever);

Would that work?

No, it will give you a compiler error. No matter what object "whatever" is
at
runtime, you're calling it as an Object, and Object.clone() is protected.

Sun has acknowledged that clone() is screwed up. No matter what you try, you
can't clone an object unless you know its type beforehand (at compile-time).
