> This seems possible if the payload in an HttpResponse is an 
> InputStreamPayload and the HTTP status code received is a 5xx.
> The BackoffLimitedRetryHandler can hit this line to release the payload from 
> a request, which will close the stream: 
> https://github.com/jclouds/jclouds/blob/master/core/src/main/java/org/jclouds/http/handlers/BackoffLimitedRetryHandler.java#L99
> Then the CinderErrorHandler attempts to read the stream here after the 
> HttpResponse is passed off to it:
> https://github.com/jclouds/jclouds/blob/master/apis/openstack-cinder/src/main/java/org/jclouds/openstack/cinder/v1/handlers/CinderErrorHandler.java#L42
> I would like to be able to write a test to reproduce this, but it doesn't 
> seem that I can set the payload correctly in the VolumeApiExpectTest to 
> trigger this. (I get a null payload instead of an InputStreamPayload when 
> trying to build an HttpResponse with the latter.)
