I agree that it would be good to aim for interoperability here.

I don't know of a spec, if you don't find one after some searching it
may be something we want to go back and ask Sun.  I recommend that you
don't reverse engineer their implementation/format to figure it out.
In the meantime we shall have to remain incompatible.
