[cdi-dev] CDI 2.0 first Face to face meeting feedbac

[Jozef Hartinger]

CDI.current() is the only problematic bit. Otherwise, there is no reason 
why running multiple CDI containers at the same time should be 
prohibited. I think we could limit CDI.current() usage in 
multi-container environments and say that a CDI instance obtained from 
boot.initialize() should be used instead of using CDI.current().
