By the way, Graham, I have no idea whether you can or cannot clone the object you get, but the object you get is not an instance of Enumeration (even though it has the type of Enumeration) but is an instance of an anonymous inner-subclass of Enumeration. So, your reason for not cloning it are not valid. Maybe it is cloneable. Have you tried? Cannot see right off why it would not be cloneable. Maybe you cannot because it cannot be casted. However, did I not read something about there being a way around casting in j2sdk1.4.0-beta3? Why don't you wrap the class and stick in your own inner class with a method giving an Enumeration that allows you to reset the cursor on the array so that you can reuse the Enumeration object?
