this is a dummy compareTo. It is just a placeholder until the proper
code is inserted.

Then it should use
return 0;
as that is at least a consistent implementation (only one equivalence class).

Still better, IMHO, is

public int compareTo(Object o) {
throw new UnsupportedOperationException("FIX ME!");
}

(This is approximately what NetBeans generates for you when you tell
it to implement the missing methods required by an interface or by
an abstract superclass.)
