This is just to inform the list that we have updated our patch to the 
release of the JSR 308 compiler from 21/8. So the patch is now 
compatible with the JSR 308 compiler. The updated patch is still 
available from here:

We are considering to slightly extend the patch to allow multiple 
supertypes for annotation types (while forbidding that different 
annotation types with a common subtype declare the same "method"). If 
there are people on the list who would find multiple supertypes 
desirable or have use cases, please let us know.
