Currently, there is no way to do so. Generated code is a combination of byte code and data. We could serialize everything, but we have not had time to investigate. Another smaller other issue is that, as a first release, the runtime has been quite fluid and caching would require versioning to make sure the cache is valid.
On the flip side, there is a byte code live cache maintained by Nashorn, which should handle reuse per session (primarily for server side apps.)
