-------------------------------------

Error occurs when the set is loaded in a new session, but not when the set is being populated.

--------------------------------------

This seems to be the same as my problem. Here my description:
Since cr3 java.lang.ClassCastException: java.util.HashSet cannot be cast to=
 java.util.SortedSet in PersistentSortedSet.tailSet

I've got a sorted to-many mapping, wich causes the above ClassCastException=
 since cr3 (it works fine in cr2).
The mapping is:

<set name=3D"Elements" inverse=3D"true" sort=3D"x2.elements.baseImpl.Elemen=
t$ComparatorByElemNo" >
       =09<key column=3D"INSTALLATION"/>
        <one-to-many class=3D"x2.elements.baseImpl.Element"/>
</set>

Here the instance variable:
private SortedSet<Element> elements =3D new TreeSet<Element>(Element.getCom=
paratorByElemNo());

I execute the following line of code:

SortedSet<Element> tailSet =3D elements.tailSet(tmp); // Here I get the Cla=
ssCastException

Immediately before the call to tailSet I have the following in the debugger=
:
this=09Installation  (id=3D32)=09
=09elements=09PersistentSortedSet  (id=3D90)=09// the object on which I cal=
l tailSet
=09=09cachedSize=09-1=09

=09=09set=09null=09=09=09// obviously not fetched yet

=09=09tempList=09null=09
=09id=091=09
=09name=09"in1"=09
=09nextElemNo=095=09
=09nextTrxNo=092=09

now executing the line:
        SortedSet<Element> tailSet =3D elements.tailSet(tmp);

Immediately after the call (when the exception is raised):
in1=09Installation  (id=3D32)=09
=09elements=09PersistentSortedSet  (id=3D90)=09
=09=09cachedSize=09-1=09
=09=09comparator=09Element$ComparatorByElemNo  (id=3D94)=09

=09=09session=09SessionImpl  (id=3D101)=09
=09=09set=09HashSet<E>  (id=3D138)=09=09=09// could this be the problem?
