JClouds does not honor security group against OpenStack

Version 2.5.1 of the JClouds plugin added the ability to define Security Groups that VMs should launch under. I've seen in the logs that it is setting something related to it but VMs are still being forcibly created in the jclouds-<instance_name> security group which eventually gets deleted when no more slaves are in it and not recreated on the next slave creation.
