Ummmm. You had:

    <set name=3D"permissions" table=3D"act_perm">
      <key column=3D"permission_id"/>
      <many-to-many column=3D"actor_id" class=3D"Actor"/>
    </set>


I changed to:

    <set name=3D"permissions" table=3D"act_perm">
      <key column=3D"permission_id"/>
      <many-to-many column=3D"actor_id" class=3D"Permission"/>
    </set>

And everything fine. I can't possibly believe that this is a change in beha=
vior from 2.0.2!

Description:
After updateing from 2.0.2 to 2.2 I have got strange problems with joined s=
ubclasses. After creating some classes and insert it into a Hibernate sessi=
on, I get during commit an exception (see below).
However if I exchange my log4j.xml by a log4j.properties everything is work=
ing well!
I know it sounds strange, so I will attach the example to this issue.
