Description

When restarting Brooklyn (using a version from a couple of months ago - timestamped 20160609.1043), it failed - the log showed the exception below.

While offline, the VM for this NginxController had been terminated.

The underlying exception means that entity.getAttribute(Attributes.HOSTNAME) was null.

This should not stop rebind from working!
