pardon my ignorance, but is there any plan to allow dynamic slot/field
access?...
ok, I am starting out just implementing my own VM with little familiarity with
this framework in general (at this point I have little idea if it will actually
be compatible), my tweak was partly to add the ability to have usable fields in
interfaces (AFAIK, this is not allowed in standard JVMs).
ok, from what info I can find, interfaces in my case work a little differently.
there is actually almost no structural coupling between interfaces and object
methods. instead, a set of hash tables is used, and the slot/method handle from
the interface is used to lookup the appropriate method in the object via the
hash tables (actually, a set of single largish hash tables is used for managing
the entire object system).
at present, the object system doesn't bother to verify that classes implement
interfaces.
(granted, some other much more questionable things are done with interfaces as
well in my case...).
the result is that it is possible to have an interface that contains the fields
in question, and use it to access the given slots in whatever object it is
given, and I could go this route.
alternatively, it could also be possible to not have a valid class in the
FieldRef (like leaving it NULL), and using this as a general indication to
dynamically lookup the slot.
so, granted, people here probably wont care about anything I am doing, but it
would be nice to have a clearer idea what the plans are.

We don't make an invokedynamic.jar. (Unless Remi does?) I think you are
looking for JSR 223, not JSR 292.
Good luck,

Do you know the location ?
