We'll be working on deployment next year that is not tied to specific versions of drools. The reason for this is that the Packge is really just a cached form representing the DRL, to avoid compiling drls on the client. We actually just serialise the resulting objects. But internally we do a lot of changes as we add features, so binary compatability of these cached objects is not easily and cheapily possible.

In the future we hope to produec a simpler intermediary format that will be durable across different versions of drools. It will require the clients to do a bit more work, as it won't be as cheap as serialisation. But we hope that it'll be an acceptable trade off.

Seems that upgrading my Guvnor install to match the version Drools in my
project has done the trick to some extent.  Still dealing with some errors,
but the original error has not presented itself.
