Logging the error code and returning with no read and not throwing an exception I believe would still work since the revocation information would be missing.  I'm wondering though if this needs to be a separate issue given that we're talking about a different use case, and one that involves the behavior of HttpURLConnection when dealing with different response codes.  I'll also check to see if there are existing tests that make CPV checks against URIs that have non-200 response codes.
