please ask these questions on the suer mailing list, this mailing list
is for questions about developing drools internals, not using drools.
Did you re-compile your packages when you changed drools versions? the
client, the server and the compiled packages must all be of the same
version.

This looks like a serialization problem. If you are sure your client,
server, packages are all using exact same version, then this might be a
bug. Could you please file a jira for this. A test case which can be
used to reproduce the problem would be helpful. Thanks.
Cheers,

Hi Jervisliu,
I posted an issue in Jira. I suppose that the problem is clear. whenI access
to a package deployed with Guvnor from a KnowledgeAgent, I get Serialization
exception.
Hope it will be fixed.

I think https://jira.jboss.org/browse/BRMS-320 is fixed now. I can't change
the status of the issue because of lack of permissions, but I think I fixed
it. Could you please try it out and confirm it?
