Fred Bricon commented on JBDS-3739:
-----------------------------------

[~rgrunber] the BZ you mentioned is about an IIOBE caused by empty tags. The NPE is a side effect. It's unclear whether [~mlabuda] hit that NPE caused by a similar IIOBE. Anyway, I think the DockerConnection.listImages implementation still leaves some way to end up with null value. It should prolly be fixed by initializing the images variable to an empty list, to ensure it's never ever null.

> When you set up cdk and start it for the first time, docker connection is properly set up and functioning. But when you restart cdk in the servers view, docker connection will no longer work.
> This is caused by a bug in vagrant-service-manager 0.0.4:
