  The problem usually occurs in the first call of the
  application.  Restarting the application usually solves the
  problem.   The null object is a CDI bean.

  ****************************************************************
  JAX-RS was registering a null ejbInterceptor, which caused a
  null pointer exception when CDI processed the list of EJB
  interceptors
  

Problem conclusion

• A null check was added to the loop where CDI processed the
  list of EJB interceptors.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.5.16 and liberty 19.0.0.10.  Please refer to the
