Ignasi Barrera commented on JCLOUDS-558:
----------------------------------------
This is the API call jclouds is using to get the list of nodes:
http://docs.openstack.org/api/openstack-compute/2/content/GET_OS-EXT-IPS-MAC-v2_getServersDetailed_v2__tenant_id__servers_detail_ext-os-server-os-ext-ips-mac.html
It returns an image object and not a String. I don't really know why your
OpenStack installation is returning a String there, but adding a check for an
empty String does not seem to be the right way to fix it (why not considering
also numeric or even boolean values there, or just catch any parsing error for
that field?). The API seems to be returning something different than what is
said in the docs, so let's first investigate a bit and try understand why, and
then we'll be in a better position to apply the right fix.
Let's see if the stackers can give some light here!
