This might be due to the way we handle class literals. Class literals for
interfaces if not referenced during the initial compile might cause that
error. The error should go aways if you restart SDM.

The offending sequence is

0) Suppose initially you have (interface A, class B and class C) and start
SDM.
1) Now edit class B to add a reference to A.class and recompile with SDM
(do not touch A at this time nor anything that makes it recompile) . This
should work fine because the literals that are referenced but whose classes
where not part of this compile will be generated in the epilogue.
2) Now edit class C in any way that does not make B or A recompile. Here
you will have an error like the one you described.

If you restart SDM at this point it should work.

I'll get a fix for this tomorrow.
