The RMI-IIOP implementation of putFields/getFields for serialization
actually sends and expects a java.util.Hashtable with the expected
fields.

It should do something such that it maintains wire compatibility
with older versions of a class that didn't use putFields/getFields --
writing the fields in the order of the older class (probably
defined with serialPersistentFields).

See the HookPutFields and HookGetFields classes in

com.sun.corba.se.internal.io

InputStreamHook.java
and
OutputStreamHook.java

Note that if version 1.0 of a class uses putFields/getFields from the start, it will work fine. However, this serialization mechanism is specifically intended for maintaining backwards compatibility.
