Java almost never does a deep copy, any time. Even .clone() does not
deep-copy, it does a shallow copy.
When you add d to alist, you add d, the reference, nothing else. Java
always uses semantics which are equivalent to pointers in C++.
Vector<Date*> alist = Vector<Date*>();
Date *d = new Date();
alist.add(d);
Or something like that, it's been a long time since C++.....
