Serialised Packages are treated as just a "cache" as they can be 
re-constituted from .drl. We do not guarantee any compatability between 
any different releases.

Longer term we want to look into achieving something that provides 
pre-compilation while also compatability across versions, but the 
codebase needs a lot of refactoring to make that easy to do.
