If I am seeing it correctly all "special classes" are only special
because they implement java.util.Map. So we would write:

  // special case bootstrap classes that implement Map
  if (x.getClassLoader() == null && x instanceof java.util.Map)

That depends on whether or not we actually want all these classes to us
the special MapPersistenceDelegate.

Cheers,
