Fixed in the next patch. Beginning with the patch, the cache will now be agnostic as to the path prefix containing the class location. Rather, the cache will store which path should be used, rather than the value of the path, e.g. "VW_CORE_PATH" rather than what VW_CORE_PATH points to. Also the cache expiry is fixed per my previous post.
With this change, the cache should now be portable across different systems if restoring from a backup on a different system, such as for server migrations, or creating test installations.
