Weld throws CNFE

I upgraded JBossAS 6.0.0 from Hudson build 2182 to 2199 and thus to Weld 1.1.0 CR1. Now I'm getting a CNFE (see stacktrace below).

The EAR project consists of an ejb and of a web module. It is setup with JBossTools 3.2.0.beta1. I'll attach
a) My sources
b) The whole eclipse project.
