I don't mind continuing to debate the overall approach a bit; it's mostly a
discussion of priorities. But IMHO the hooks in the Mapper class are a useful feature,
whether or not we prioritize using them in M2. Having them in a JBoss Web release this
week lets us go either way for M2. The rest of the implementation is in AS trunk itself,
where the cutoff is 2 weeks later.
Bela's point about 2 mechanisms for delayed deployment is a good one. The critical
thing is getting the server ready to handle requests ASAP; you can offload heavy
non-critical stuff off the main thread. But if you do that, JBoss Web needs to know about
the webapps that will be coming on later, otherwise the server isn't really
"ready to handle requests". The Mapper stuff I did provides the hooks to make
that doable. A user request triggers the deploy if the background thread hasn't gotten
to it yet. Some simple coordination logic in the "activator" ensures it the
activation only happens once.
