The _read(InputStream istream) method reads data from istream and initializes
the value field of the Holder with the unmarshalled data. What should happen
when there is no data to unmarshall?

We have a small test case that uses
  org.omg.cosNaming.list(int how_many, BindingListHolder bl, BindingIteratorHolder bi)
in a situation in which either bi.value==null or bi.value.next_one(bh)==false
(where bh is a BindingHolder instance).

Using idltojava and tnameserv, bi.value!=null. There are third party ORBs for which
bi.value==null. The correct behavior needs to be written down somewhere so that
Java can interoperate with third party ORBs.
