We had a very similar problem concerning AllPermission objects
being sent via RMI (and dont ask me why we are doing this !!!) from
a Linux server running 1.2rc2 and a Windows client running 1.3beta.
As a result, an Unmarshalled Exception was thrown.
The reason seemed to be that SUN changed the way the
AllPermission object was generated from 1.2 to 1.3 by using an
AllPermissionCollection object. So the client got an object of type
AllPermission and tried to retrieve an AllPermissionCollection
object from the 1.2 server, which could not work.
SUN changed a few things in 1.3 and I would not be surprised if
more of those things arised.
