Compiling to bytecode files

[Jim Laskey (Oracle)]

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.)

Cheers,

In Rhino, I can create class bytecode for me that I can store in files and then simply load the next time the code needs to be accessed. Specifically, Rhino has a interface named org.mozilla.javascript.GeneratedClassLoader that lets me reload the bytes.
