No. See the section in "Missing Stuff" (#3) about this. Since you
can't read annotations until you have classloading, if you need to make
additional classloading changes, it has to happen in a second phase
where dependencies are recalculated, and the processor has to be aware
of that fact; in addition the proper module dependencies (and thus the
corresponding MSC dependencies) have to be established between the
deployments.
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.
