bean-discovery-mode="annotated" in cdi beans.xml

[evernat]

from beans_1_1.xsd :

               It is strongly recommended you use "annotated". 
               
               If the bean discovery mode is "all", then all types in this
               archive will be considered. If the bean discovery mode is
               "annotated", then only those types with bean defining annotations will be
               considered. If the bean discovery mode is "none", then no
               types will be considered.
