It looks like the extension api is returning some extensions without the namespace field, and jclouds expects it to always be present [1] (jclouds binds extension namespaces and aliases to Java API classes and uses that to resolve which api to return for each extension).
Could you enable the "jclouds.wire" logs [2] and see what is being returned for the list extensions call? Any idea why it is not returning the extension namespace? @Zack is it OK for the extensions not to return the namespace? is this something that has changed in newer OpenStack versions? I.
