When creating a slave machine i'm seeing this NPE regularly. It causes the creation of the slave to fail, but the machine is still provisioned in cloudstack. I would have expected that the machine would be detroyed once a part of the provisioning fails.

Installed version of jenkins-jclouds is 3.2.1, Jenkins is at 1.508
