Ok, I'll take a look. I think this adapter work is very important, it
would be good to discuss problems/progress on the dev list too.

Is that an issue with JCHEVM or the JAR files do you think?

I agree that producing an adapter to redirect from Classpath's
hard-coded assumptions is the right answer.

Ah, ok -- I'll try and do the timeshift thing, but if there are fixes
that are required in Harmony classlib to make things work/easier for you
they will be applied to the current HEAD, and we can discuss what is
required for them to work in your local sandbox.

(Two months ago:) IIRC there is an explicit call to
System.loadLibary("hynio") in the class libary code, so why do you need
to make that into a Classpath-specific call?
