Adaption of InjectionTarget does not take effect on a ProcessInjectionTarget event for an Extension in a jar of WEB-INF/lib

If an Extention is defined in a jar located in WEB-INF/lib then that jar will receive ProcessInjectionTarget events but modification of the InjectionTarget, for example adapting the InjectionTarget does not have any effect. The methods on the adapted InjectionTarget instance are never invoked.

I am using a build of Weld from the trunk that Roger Kitain gave me to test.
