I've taken this approach.
Since I doubt the N will be big. 

Adding VersionComparator:

  | public interface VersionComparator<T extends Version,
U extends Version>
  | {
  |    /**
  |     * Compare the two version impls.
  |     *
  |     * param t T version impl
  |     * param u U version impl
  |     * return compare the two version impls
  |     */
  |    int compare(T t, U u);
  | }
  | 
and a VersionComparatorRegistry singleton to keep all the
known implementations.

And changing the Version class to delegate the compareTo to
the registry:

  |    public int compareTo(Version v)
  |    {
  |       VersionComparatorRegistry registry =
VersionComparatorRegistry.getInstance();
  |       return registry.compare(this, v);
  |    }
  |
