Romain,

Depends on how you're trying to instantiate it.  There is a CdiBusBean
provided by CXF which does what you're trying to do -
https://github.com/apache/cxf/blob/3.1.x-fixes/integration/cdi/src/main/java/org/apache/cxf/cdi/CdiBusBean.java#L40
,
take a look at the create method.

I was actually contemplating removing the @Inject from the CXFCdiServlet's
set method, it seems to work inconsistently.  However, i suspect that your
issue is that you're getting a Bus registered as a valid CDI bean
(bean-discovery-mode=all?).
