As is often the case, Jason has made a liar out of me. :-)

This time, he has modified Jandex to be able to read annotation values 
as well - the cost of doing so turns out to be much less than 
anticipated - so, we can process annotations much earlier in the 
deployer chain.  This is very good news - it gives us considerably more 
flexibility in our deployer design.  Se let's move annotation processing 
to, say, "parse" phase.
