If you're looking for a function that will return the current size of
the list, try the LinkedList.size() method. The function you're using,
ListIterator.nextIndex(), is working as advertised - the only thing that
should change its return value is your use of ListIterator.next() or
ListIterator.previous().
If this were a bug, it's not likely to be Linux-specific... the
container classes are themselves implemented in Java and work the same
everywhere.
