CDI provides the mechanism of @Alternative (as well as @Specializes) implementations. As soon as MyFaces CODI provides a default implementation as CDI bean, it's possible to provide a custom implementation via @Alternative (or @Specializes) (+ the corresponding std. CDI config). However, some CDI artifacts like CDI-Extensions (javax.enterprise.inject.spi.Extension) and Interceptors (javax.interceptor.Interceptor) don't support the mechanism for providing alternative implementations. Therefore, MyFaces CODI allows to create a custom implementation of the ClassDeactivator interface (or AbstractClassDeactivator).
