For the consuming part have a look at http://www.agorava.org/ (created by CDI Spec Lead Antoine and myself as a result of a "Social" JSR being turned down by the EC and to succeed Seam Social)
Except Mockito there are very few parts that are not based on standards or can be under Java EE 8 (with a little work Jackson Binding can be replaced by JSON-B 1.0)

CDI (1.1) and JAX-RS 2.0 are already used.
