Rest-client can't be used without opentracing subsystem present in config

Trying to provision the following set of galleon layers:
jaxrs ==> for jaxrs and rest-client
microprofile-config

I am getting an NPE. If open-tracing is provisioned along with jaxrs, no NPE and client injection works fine.

java.lang.NullPointerException
