Re: [weld-dev] Initialising newly registered beans

Why are you doing this?
The ShutdownManager and ParametersFactory beans are currently discovered using
conventional classpath scanning. IE: there is a /META-INF/beans.xml in the weld-se jar.
Therefore when I create a shaded jar of Weld SE, every class in the dependant jars gets
picked up as a simple bean, which obviously wreaks havoc.
We had this working properly, just passing in the classes to scan in
the past using bootstrap.
Not sure what you mean, but if it's easier I'm all ears :).
All of this stuff you are accessing is internal impl detail in Weld,
it is *not* part of the Weld SPI...
Yeah I know but since this part of Weld SE and doesn't need to be portable I just went
with the easiest classes to work with. If I need to continue down this path I'll hit
you up for some pointers.

WeldBootstrap:199 I could call it.getBeanDeployer().getEnvironment() ... but I could be
