Adding Classes at Run-time
by Jason Lee
I have an odd question. I have a situation where I'm manually opening a
JAR and adding its classes to the ClassLoader. What I'd like to be able
to do is have Weld scan these classes for any relevant annotations and
take the proper actions, just as if the JARs were in the classpath when
the application started. I've been staring at the JavaDocs (build
locally, btw, as I can't find them on the web :| ) but I don't see any
way to request that Weld inspect a given class. Is it there and I'm
missing it? Am I going to have cobble together that functionality? Am
I asking for something that can't be done (right now)? Any nudges in
the right direction would be much appreciated. :)

Modularity
by Pete Muir
I was talking to Ales and Lincoln on IRC about how Weld handles modular environments. Whilst we have a full structure for representing module visibility relationships, we don't have any way of expressing that a bean is private to a module - all beans are exported. I don't think this really is consistent with how modular systems work, and so I think we need to add this to the BDA contract e.g.
public Collection<String> getPrivateBeanClasses();
I would suggest returning private/hidden classes rather than public ones here, as it means non-modular envs don't need to adjust their code much to have everything work as normal.

Conversation questions
by Nicklas Karlsson
Some conversation-related questions
1. In WeldPhaseListener.activateConversations(), it appears as if the
conversation context is never activated if an unknown cid comes in.
Shouldn't the conversation context still be active but with a transient
conversation? Moving the conversationContext.activate(cid); before the check
might work.
2. Is there any way of setting the conversation timeout globally? The
constant defined in AbstractConversationContext appears to be injected into
the constructor of the ConversationImpl. If it would be acquired from a
producer method, could it then be specialized?
3. Should we have a concept of a "foreground conversation" in Weld so that
an incoming cid to a known, non-transient conversation would resurrect the
conversation even if it has been expired (but not yet cleaned up)? If I read
the code correctly, a cid that comes in after the expire time has passed is
still taken into use for the request but at the end marked as ended and then
cleaned up as transient.
