I am not sure what you try to accomplish. Any Hibernate support in XStream
is one-way only i.e. you can marshal a Hibernate PersistentSortedSet and you
will get a TreeSet at unmarshalling time.
Note, that I have absolutely no Hibernate experience, so I don't know what
you can do with the Hibernate mapping files. All test code in Xstream was
provided by helpful users.
As far as XStream is concerned, the PersistentSortedSet is handled by the
HibernateSortedSetConverter which is derived from the TreeSetConverter. That
one will marshal also the comparator that is returned by
SortedSet.comparator().
So how does the XML for this comparator looks like that has been produced by
XStream? What do you exactly mean with "complaints"?
Cheers,
Jörg
