Morten Christensen commented on WELD-521:

My needs are:
1) Support running environments: JEE, JSE, OSGI (but I don't think this can be auto-detected - I think only the application will be able to know what the environment is, which is why a static method is good).
2) Support different versions of the same software - f.x. "standard", "professionel", "enterprise".

Both these needs affect the classpath and what classes/packages should be scanned (f.x. my app's OSGI specific classes will simply not resolve if running as JSE and maybe not under JEE) . Normally, in Java this is not a problem because the Java standard has lazy loading of classes.... But since the weld scanner loads everything, this will cause applications to "blow up" unless we have a way to customize where to look.

> Better support for dual SE and EE applications. I have some weld-using jar's that can be deployed on a Java EE and work standalone. It is possible to get this to work using both weld SE and weld EE but it is a pain. F.x. when deployed under glassfish weld will fail unless I include a few weld SE dummy classes.... Weld should either combine weld SE and weld EE OR there should at least be some support for having weld ignoring some of my classes/packages depending on which environment it is running under.
