I think you'll find an example of this in natReference.cc:

void
::java::lang::ref::Reference::create (jobject ref)
{
  // Nothing says you can't make a Reference with a NULL referent.
  // But there's nothing to do in such a case.
  referent = reinterpret_cast<gnu::gcj::RawData *> (ref);
  copy = referent;
  if (referent != NULL)
    {
      JvSynchronize sync (java::lang::ref::Reference::lock);
      // `this' is a new Reference object.  We register a new
      // finalizer for pointed-to object and we arrange a special
      // finalizer for ourselves as well.
      _Jv_RegisterFinalizer (this, finalize_reference);
      _Jv_RegisterFinalizer (referent, finalize_referred_to_object);
      gnu::gcj::RawData **p = &referent;
     _Jv_GCRegisterDisappearingLink ((jobject *) p);
      add_to_hash (this);
    }
}
