Review comment:
       I get the same failure on the master branch without this PR. I don't 
think the failure is related to this change.
   
   Without this change there is a catastrophic timing issue. If CXF isn't 
started when you try to access the Client (or SSE, or a few other things) then 
it tries to initialise the CXF HTTP stack and fails. This failure is cached and 
can only be cleared by restarting the framework, or refreshing all the CXF 
bundles.
   
   The change doesn't remove service loader (which is necessary to make the 
static use work), just the service registration. By doing it manually Aries 
JAX-RS whiteboard can delay until the services are safe to use.
