After upgrading to ivy 2.3.0 rc2, ivy:info doesn't resolve a component in Artifcatory using the url resolver (and http-components.)  Here is a fragment of the debug log from ant:

 [ivy:info] WARN: problem while listing resources in http://server/artifactory/internal-repos/com.ints.web-central/wc-feature-53/isi-wc-common-client/ with artifactory-internal:
 [ivy:info] WARN:   java.lang.NullPointerException null

 [ivy:info] using artifactory-internal to list all in http://server/artifactory/internal-repos/com.ints.web-central/wc-feature-53/isi-wc-common-client/

This same setup works in rc1.   I have attached a more complete log.  Any ideas?
