    I tried today to integrate jenkins with our openstack deployment (based on Juno) and everythings went smooth until it had to add a floating ip to the instances. At that point i get null pointer exception: {code} javax.servlet.ServletException: java.lang.RuntimeException: org.jclouds.compute.RunNodesException: error running 1 node group(fedora)
