Yes, this is a known bug. I don't recall the bug number. It's been
talked about for quite some time. However, if you look at how classes /
objects behave in Java and other languages, you wouldn't normally
expect a simple 'duplicate' function to do the right thing... that's
why you need to explicitly program how 'clone()' works in Java - the
semantics of duplicating an object are rarely the same as just
duplicating the 'struct' that represents it.
